(a -> H₂) will evolve with Ph-CH₂-Br
(b -> AgCl) will form with Ph-CH₂-Br
(c -> Ph-CO₂H) will form with Ph-CH₂-Br

Hint: Only primary amine gives carbylamine test

The carbylamine test is given by primary amine only. 

The structure of the given compound is as follows:

, , , 

The first two compounds are secondary amine, the third compound is a tertiary amine and the fourth compound is a primary amine.

Thus, only 2,4-dimethyl aniline gives the carbylamine test and the reaction is as follows:
