Answer:
Correct Answer: D
Solution:
In gemdihalide both the halogen atoms are present on the same carbon atom while in vicdihalide both the halogen atoms are present on adjacent carbon atoms.
$ \underset{Gemdihalide}{\mathop{CH_3-CHBr_2}} $
$ \underset{vic\text{-}dihalide}{\mathop{\underset{\underset{Br}{\mathop{|}}}{\mathop{CH_2}}-\underset{\underset{Br}{\mathop{|}}}{\mathop{CH_2}}}} $
