Question

Which of the following is constant along an indifference curve?

A.

Price

B.

Technology

C.

Output

D.

Utility

Correct option is D

​​The correct answer is (d) Utility.
Along an indifference curve, utility remains constant. An indifference curve represents all combinations of two goods that give a consumer the same level of satisfaction or utility. Therefore, the utility derived from the different combinations of goods on the curve remains the same.
  • Price: Price is not constant along an indifference curve. It may change based on market conditions, but it is not a factor in the definition of an indifference curve.
  • Technology: Technology is unrelated to the concept of an indifference curve, as it pertains to the production side of economics.
  • Output: Output is not constant along an indifference curve, as it refers to the production of goods, whereas the indifference curve is about the consumption of goods.​
Information booster :
  • An indifference curve helps illustrate a consumer’s preferences between two goods, holding their overall utility constant.
  • It is used to study consumer behavior, choice theory, and utility maximization in economics.
