Question

According to the law of variable proportions _________.

• A. the marginal product of an input initially rises and then after a certain level of employment, it starts falling
• B. the TP is a positively sloped curve
• C. the AP curve is inverse U shaped
• D. none of these

Answer 1

The correct option is A the marginal product of an input initially rises and then after a certain level of employment, it starts falling
