参考答案: B
本题详细解析: B
image Revenue is maximised at the level of output where MR = 0. As output approaches this point from the left, MR is positive, so more output increases total revenue. After this point, MR is negative, so additional output causes total revenue to decline.
Choice A is the profit-maximising level of output, and Choice C is the allocatively efficient level of ouput. At point D, total revenue is minimised, because P = 0.
