Question:

In case of perfect substitute, the marginal rate of substitution ________.

Options:

Diminishes

Rises

Does not apply

Constant

Correct Answer:

Constant

Explanation:
 Of the above options, Constant is the answer.

In the case of perfect substitutes, the marginal rate of substitution (MRS) is constant. This means that a consumer is always willing to trade one unit of one good for one unit of the other good. This is because the two goods are perfectly substitutable, so the consumer does not care which good they consume.
