Choose the correct feature of indifference curve from the following :

Indifference curves never intersect each other

The correct answer is option (2) : Indifference curves never intersect each other

The reasons why indifference curves never intersect each other lies in the definition of indifference curves and the underlying concept of consumer preferences. An indifference curve represents different combinations of two goods that provide the consumer with an equal level of satisfaction or utility. If two indifference curves were to intersect, it would imply that at the point of intersection, the consumer is indifferent between different bundles of goods on both curves. However, this contradicts the concept of indifference curves, which implies that each curve represents a unique level of satisfaction. Therefore, to maintain consistency with the concept of consumer preferences and utility maximization, it is essential that indifference curves do not intersect.

The other options are incorrect features of indifference curves:

Indifference curve slopes upward from left to right: A core feature is that indifference curves typically have a downward slope, reflecting the concept of diminishing marginal utility. As you consume more of one good, you're likely to be willing to give up less of the other good to maintain the same level of satisfaction.

Lower indifference curve gives higher level of utility: The opposite is true. Lower indifference curves represent lower utility levels.

Higher indifference curve gives lower level of utility : The opposite is true. Higher indifference curve gives higher level of utility.
