Geometrical Isomerism arises due to different arrangement atoms/groups around a system where free rotation of bonds is restricted.

Generally in a geometric isomer, the atoms are bonded by a double bond that does not freely rotate, but it can also happens because of the ring structure.

The other condition to exhibit geometrical isomerism is, two atoms or groups attached to the molecule with the doubly bonded carbon atom must be different. However, it doesn't matter whether the left side groups are the same or different on the right side.

This compound shows geometrical isomerism.

Hence option B is the answer,
