sales reps A. vi.行军;示威 B. n.赞成,同意;批准 C. vi.腐烂;衰败 n.腐烂 D. n.推销员

sales reps refers to "推销员" in Chinese. The term combines "sales" (销售) with the abbreviation "reps" (representatives), specifically denoting professionals who promote and sell products or services. Among the options, this matches D.

In business contexts, sales reps act as the direct link between companies and customers, responsible for building relationships, demonstrating product value, and closing deals. Unlike the other options—A (marching/protesting), B (approval), or C (decay)—D directly corresponds to the occupational role described by "sales reps."
