The incorrect statement regarding the product of reaction
A $\to_{}^{}$ B
(alkene)

A is trans and B is a racemic mixture if R $\neq$ R'

B is optically inactive due to external compensation if R $\neq$ R' and optically inactive due to internal compensation if R=R'.

A is trans and B is a meso compound if R = R'

A is trans-alkene and B is always racemic mixture irrespective of the face whether R and R' are the same or different.
