JEE Main 2016 Chemistry question

In the Hoffmann bromamide degradation reaction, the number of moles of NaOH and used per mole of amine produced are:

Answer: (2)

The balanced equation for the degradation of a primary amide to a primary amine with one fewer carbon is

RCONH_2 + Br_2 + 4NaOH → RNH_2 + Na_2CO_3 + 2NaBr + 2H_2O.

Counting the hydroxide: one mole deprotonates the amide nitrogen, a second mole removes the
