Quizplus · Accepted Answer

A stereocenter is an atom that has four different groups attached to it. In order to have four different groups, the atom must have four single bonds. Therefore, choice A is the correct answer. Choices B and C are incorrect as they do not have four single bonds, which is a requirement for a stereocenter. Choice D is incorrect as not all bonding arrangements can result in a stereocenter; only those with four different groups attached to the atom.
