Quizplus · Accepted Answer

Mercaptoethanol can reduce disulfide bridges, which are represented by the S-S bond in molecule B. The reduction results in two sulfhydryl (-SH) groups, which are shown in molecule B after the reaction. Molecules A, C, and D do not contain a disulfide bridge and therefore cannot be the result of mercaptoethanol reduction.
