Doubt from GOC

#21

Why it will be option 2

#22

Here most basic nitrogen is that which participate in reaction in option B and here acid base reaction takes place so H+ will react with most basic nitrogen.

#23

And in option A lone pair of nitrogen is not available for proceeding any reaction with H+ ion from HCl.

#24

N attached to benzene has lone pair participating in resonance,, so other N atom will participate in acid base reaction..am I right??

#25

Yes
