The law of diminishing marginal returns: a. states that each and every increase in the amount of the variable factor employed in the production process will yield diminishing marginal returns b. is a mathematical theorem that can be logically proved or disproved c. is the rate at which one input may be substituted for another input in the production process d. none of the above

d. none of the above

Explanation:

In Economics, The law of diminishing marginal utility states that as the unit of a good or service consumed by an individual increases, the additional satisfaction he or she derives from consuming additional units would start decreasing or diminishing as the units of good or service consumed increases.

Also, the marginal utility of goods and services is the additional satisfaction that a consumer derives from consuming or buying an additional unit of a good or service.

For example, buying a chocolate bar and eating it may satisfy your cravings but eating another one wouldn't give you as much satisfaction as the first due to diminishing marginal utility.
