Q.

The marginal, average, and total product curves encountered by the firm producing in the short run exhibit all of the following relationships except:

When the total product is rising, the average and marginal product may be either rising or falling.
When average product is at a maximum, marginal product equals average product, and total product is rising.
When marginal product is at a maximum, average product equals marginal product, and total product is rising.
When marginal product is negative, total product and average product are falling.
