Why the answer is A, and why the others tempt you.
By Markovnikov's rule the hydrogen adds to the carbon that already has more hydrogens (the CH$_2$ end), and the bromine goes to the middle carbon, via the more stable secondary carbocation, giving 2-bromopropane. 1,2-dibromopropane forms with Br$_2$, not HBr.
