Text Solution

Verified by Experts
The correct answer is:
B

Both cis and trans form of the given complex are optically inactive due to the

presence of plane of symmetry and alternate axis of symmetry.

A molecule is said to possess -fold alternate axis of symmetry, if rotation of molecule along the axis by an angle of followed by reflection in a plane perpendicular to the axis results in the same structure.
