why NH3+ is favored over NH2?

NH2 is also electron withdrawing group which is acidic.

Thanks for your help.

Morning'. So your mixing up two concepts. This is not testing aromatics or whats electron donating or withdrawing. Its just an amino acid and its testing to see if you know how things will appear in different conditions. Here the NH2 group has a lone pair so if you put this thing in acid (lots of H+ around) it will protonate the lone pair and all groups will appear in their protonated form (COOH AND NH3)
If however you put it in Base it will be COO- and NH2

Furthermore NH2 is one of the strongest activators there is.

NH2 is activator and electron donating. NO2 is electron withdrawing and deactivator. don't mix them up. G luck
