D Correct answer
Explanation

Correct answer. Hydrazine (N2H4) is a nitrogen hydride. In Raschig process, it is prepared by the reaction of ammonia with sodium hypochlorite in a dilute aqueous solution and Boric acid is a weak monobasic acid. It is not a protonic acid, but acts as a Lewis acid by accepting an electron pair from a hydroxyl ion. Hence, statements 1 and 3 are false.
