Step 1: Analyzing Geometrical Isomerism in Cycloalkanes
For a compound with an exocyclic double bond, geometrical isomerism occurs if the exocyclic alkene carbon () and the ring system are both unsymmetrically substituted. In Structure A, the ring is unsymmetrically substituted due to the methyl group at the 3-position, and the exocyclic carbon is attached to H and Cl.

Step 2: Conclusion
This dual lack of symmetry allows for the existence of  and  isomers.
