surely A will not show geometrical isomerism , so as d ( spiranes don't show g.m. )

well i am getting some different answers

A → P Q R

B→ Q S

C→ P R

D→

sry got nothing for D

P can show geometrical isomerism cis(both methy grps out of the plane) trans(one methyl grp inside and one out of the plane)..

R is achiral coz it's a 2d compound..
