Quizplus · Accepted Answer

The given compound has four substituents on one carbon atom, and two on another. The configurational isomers arise due to the different arrangement of these substituents. Thus, A and B differ in the arrangement of the substituents on the first carbon, A and D differ in the arrangement of the substituents on the second carbon, and B and D differ in the arrangement of both sets of substituents. C does not have any configurational isomers because it has a symmetrical arrangement of substituents. Therefore, the correct choice is E, which includes all the possible configurational isomers - B and D, which differ in both sets of substituents, A and B, A and D, and C and D.
