A. producing at the point where price is equal to MR.
B. producing at the output level where marginal revenue equals average variable cost and charging a price along the demand curve that corresponds to the output rate.
C. producing at the output level where marginal revenue equals marginal cost and charging a price on the demand curve that corresponds to the output rate.
参考答案：C
解析：
A monopolist will maximize profits by producing at the output level where marginal revenue equals marginal cost and charging a price on the demand curve that corresponds to the output rate. This will maximize profits. The goal of the monopolist is to maximize profits, not revenue (as suggested by the response : "setting the quantity as low as possible" ).
