The law of diminishing marginal utility states:

  • A The supply curve slopes downward
  • B Your utility grows at a slower and slower rate as you consume more and more unit of a good.
  • C The elasticity of demand is infinite
  • D None of the above

The correct answer is B. Your utility grows at a slower and slower rate as you consume more and more unit of a good.

The law of diminishing marginal utility states that the Satisfaction derived from consuming successive units of a commodity will diminish as the total consumption of the commodity increases. In other words, the total utility increases as more of a commodity is consumed but increases at a diminishing rate.
