The correct answer is: C. Higher level of satisfaction.
An indifference curve is a graph that shows all the combinations of goods and services that provide the same level of satisfaction to a consumer. A higher indifference curve represents a higher level of satisfaction, because the consumer is able to consume more goods and services.
Option A is incorrect because it is the minimum level of satisfaction. Option B is incorrect because it is a point on an indifference curve, not the curve itself. Option D is incorrect because it is the highest level of satisfaction, which is not possible to achieve.
