Read the following passage and answer, question.

A consumer is a rational individual who knows, what is good and bad for him/her. So he always tries to achieve the best to get maximum satisfaction. Thus, the consumer chooses the set of bundles as per his preference which is best for him. The consumer always prefers to move to a point on the highest possible indifference curve given on the budget set. The slope of the budget line is the rate at which the consumer is able to substitute one good for the other in the market.

The indifference curve is :

Convex

The law of Diminishing Marginal Rate of Substitution causes an indifference curve to be convex to the origin. This is the most common shape of an indifference curve.
