The law of diminishing marginal product is reflected in a firms short run production function and also several of its costs curves. The shapes of which cost curves reflect the law of diminishing marginal product:
A- total cost, total variable cost, average variable cost, average total cost, and marginal cost
B- total fixed cost, total variable cost, average variable cost, marginal cost, and average total cost
C- total variable cost, average variable cost, average fixed cost, average total cost, and marginal cost
D- total cost, total variable cost, average fixed cost, marginal cost, and average variable cost
