For (b), based on my understanding, only A is capable of forming enantiomers because the left carbon can have 4 different groups attached to it. Br will be added to the left carbon rather than the right as the secondary carbocation on the left will be more stable than the primary carbocation on the right. The answers then follow. Hope this is correct and that it helps!
