A、 addition to total revenue from selling one more unit of output.
B、 additional output produced by using one more unit of a productive input.
C、 gain in revenue from selling the output produced by using one more unit of a productive input.

【正确答案】 C

【答案解析】[解析] 边际收益产品(MRP)则是指增加一单位生产要素投入带来的产量所增加的收益。边际收益产品等于生产要素的边际产品和边际收益的乘积，即：
MRP=MP×MR
因此，边际收益MR对应于最后一单位产品的收益，而边际收益产品MRP则对应于最后一单位生产要素的收益。
