Question

Mariana Lopez Macias · Accepted Answer

Final Answer : C, Explanation :  For a purely competitive firm, marginal revenue (MR) is constant at all levels of output, meaning it does not change as output changes. This is because a purely competitive firm is a price taker, and the price of its product is determined by the market. Therefore, the MR graph is a straight line parallel to the horizontal axis, indicating a constant MR at all levels of output.
