Correct Answer: He or she has to be a retired Chief Justice of India.

Solution : The correct answer is that He or she has to be a retired Chief Justice of India.

The National Human Rights Commission was established as a statutory body under the Protection of Human Rights Acts, 1993. It was established in adherence to the Universal Declaration of Human Rights.

Correct Answer: two year

Solution : The third option is the correct choice.

• Two-year course refers to an educational course of study that spans two years, which fits perfectly in the sentence.
• The first and fourth options are grammatically incorrect. The option two years doesn't fit in contextually with the sentence.

Therefore, the complete sentence is: "Suresh has joined a two-year course."

Correct Answer: 130

Solution : Given:
17, 51, 58, 116, 123, 123, ?

Multiply the decreasing order of the numbers starting from 3, and add 7 alternately to the given numbers –
17 × 3 = 51; 51 + 7 = 58; 58 × 2 = 116; 116 + 7 = 123; 123 × 1 = 123; 123 + 7 = 130

So, 130 is the missing number of the series. Hence, the second option is correct.

Correct Answer: 12 m/sec

Solution :

Ram beats Shyam by 200 m or 20 sec.
This means Shyam covers a 200 m distance in 20 sec.
$\therefore$ Speed of Shyam = $\frac{200}{20}$ = 10 m/sec
Also, in the 1200 m race, Ram beats Shyam by 200 m.
Distance covered by Ram = 1200 m
Distance covered by Shyam in same time = 1000 m
Now, the 1000 m distance is covered by Shyam with a speed of 10 m/sec in $\frac{1000}{10}$ = 100 seconds
So, 1200 m distance is covered by Ram in 100 seconds.
$\therefore$ Speed of Ram = $\frac{1200}{100}$ = 12 m/sec
Hence, the correct answer is 12 m/sec.

Correct Answer: Chalukya

Solution : The correct answer is Chalukya.

The Ravana Phadi Cave in Aihole (previously Aryapura or Ayyavole), a cave temple of the Early Western Chalukyas dating to the sixth century, is regarded as a significant shrine in the upliftment of early medieval Deccan architecture.

Correct Answer: quardant

Solution : The fourth option is correct.

The correct spelling is quadrant. The incorrectly spelled word quardant can be corrected by changing the position of the letter "r" after "d". It refers to one of four equal parts into which a plane is divided by two perpendicular coordinate axes.

The meanings of the other options are as follows:

• A medallion refers to a large medal or a piece of jewellery in the form of a disc.

• Elaborate means detailed, complex, and carefully designed.

• Complemented means to complete or enhance by providing something additional.

Correct Answer: epitaph

• A stela is an upright stone slab or column, typically bearing a commemorative inscription or relief design.
• Prologue is an introductory section of a literary work or play.

Therefore, the correct answer is epitaph.

Correct Answer: HMY

Solution : Given:
THC, DIU, VJE, FKW, XLG, ?

Follow the pattern as shown below to obtain the next letter cluster –

So, HMY is the missing term in the series. Hence, the third option is correct.

Correct Answer: before

Solution : The third option is the correct choice.

• Stood before refers to the act of standing while facing someone, which fits perfectly in the sentence.
• The option stood for means to support a cause, which is inappropriate in the context of the sentence. The options stood to and stood towards are wrong.

Therefore, the complete sentence is: "He stood before Ankita but could not utter a single word for quite some time."

Correct Answer: 9 km/hr

Solution : The speed of the boat in still water can be calculated using the speeds of the boat downstream and upstream.
$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$
The speed of the boat downstream (with the current) is the distance divided by the time, which is
$\frac{72 }{6 }$ = 12 km/hr
The speed of the boat upstream (against the current) is also the distance divided by the time, which is $\frac{72 }{12 }$ = 6 km/hr
The speed of the boat in still water is the average of the downstream and upstream speeds, which is $\frac{12 + 6 }{2}$ = 9 km/hr
Hence, the correct answer is 9 km/hr.
