Solution : The correct choice is the first option.

In reported speech, it's essential to make appropriate changes to verb tense, pronouns, and other elements to convey the original speaker's message accurately. 

The steps of conversion are as follows:

• The reporting verb "said" is unchanged because the given sentence is an imperative sentence.
• The conjunction "that" is used to introduce the reported clause.
• "Let be issued" is changed to the past infinitive "was to be issued".
• The time expression "next week" is changed to "the following week".

So, the correct sentence would be: The librarian said that no student was to be issued a book till the following week.
