Quizplus · Accepted Answer

The compound has two substituents, a methyl group and an ethyl group, attached to a cyclopentane ring. The prefix "cis-" indicates that the two substituents are on the same side of the ring, while "trans-" indicates that they are on opposite sides. The prefix "1-" indicates that the methyl group is attached to the first carbon of the ring, while "3-" indicates that the ethyl group is attached to the third carbon. Therefore, the correct name is cis-1-ethyl-3-methylcyclopentane (choice B).
