Answer:

second option (B)

Explanation:

The s-cis conformer is higher in energy than the s-trans conformer. The most stable conformer has bent-inward geometry which favors the π bond interaction with methyl/methylene hydrogen/carbon atom hence more crowding with consequent higher energy, this is also responsible for the higher boiling point of the s-cis conformer.
