Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

option A is correct. it shows Geometrical isomers. because two methyl groups attached to ring can be cis or trans with respect to each other.
in option B it have chiral axis so it shows option isomerism
in option c, due to double bonds if ring size is up to 7 carbons, groups attached to double bond can't change their position so it doesn't show GI
in option (d) no conditions meed to show GI. there is no two different groups on two different points
got it.???
please accept the answer if you got it ๐๐
