Correct Answer - D
`E_(2)` elimination occurs when the two atoms/groups to be eliminated occurs the two atoms groups to be eliminated are trans to each other and lie in the same plane. Since in trans 2-phenyl1-1-bromo cyclopentane
The `C_(2)H_(5)` as with respect to `C_(1)-Br` hence elimination does not occur according to Saytzeff rule. Intead `C_(5)-H` is trans to `C_(1)-Br`. Therefore, elimination occurs on this side to give-3-phenylcyclopentane.
