Suggest the product from two-substituted benzene ring
On substituting an already substituted benzene ring, you need to know which kind of substitution takes place; It is electrophillic substitution that is taking place.

Then can you now think about the correct choice? 
$\ce{-NH2}$ has a greater positive mesomeric effect (+M effect) 
in comparison to the Halogen groups.

Since the para position with respect to $\ce{-NH2}$ is already occupied by chlorine the ortho position would be attacked.

What we come to know is that since $\ce{-NH2}$ creates more electron availability in comparison to halogen it leads to "electrophilic substitution" on ortho position with respect to $\ce{-NH2}$.

And moreover $\ce{-NH2}$ group since a very very strong electron donor so once again another substitution of next bromine takes place at the other ortho position with respect to $\ce{-NH2}$.
