(c) 
Options:
Answer:
D
Solution:
(a) cis-1,2-Dimethylcyclopropane: the two stereocentres carry identical sets of groups and a plane of symmetry passes through C3 and the midpoint of the C1-C2 bond - meso. (b) trans-1,2-Dimethylcyclopropane: two stereocentres with no plane or centre of symmetry - chiral, not meso. (c) cis-1,2-Dichlorocyclohexane: two stereocentres with an internal plane of symmetry - meso.
