The correct answer is C. Equal.
A consumer is in equilibrium when the marginal utility of each good consumed is equal to the marginal utility of money. This means that the consumer is getting the same amount of satisfaction from each additional unit of each good consumed.
If the marginal utility of one good is greater than the marginal utility of another good, the consumer will want to consume more of the good with the higher marginal utility. This will continue until the marginal utilities of all goods are equal.
If the marginal utility of one good is less than the marginal utility of another good, the consumer will want to consume less of the good with the lower marginal utility. This will continue until the marginal utilities of all goods are equal.
The following is a brief explanation of each option:
- Option A: Minimum. This is incorrect because the marginal utility of a good is typically highest at the point of consumption and then decreases as more of the good is consumed.
- Option B: Highest. This is incorrect because the marginal utility of a good is typically highest at the point of consumption and then decreases as more of the good is consumed.
- Option C: Equal. This is the correct answer because the consumer is in equilibrium when the marginal utility of each good consumed is equal to the marginal utility of money.
- Option D: Increasing. This is incorrect because the marginal utility of a good is typically highest at the point of consumption and then decreases as more of the good is consumed.
