  • remains constant, rises
  • falls, falls
  • rises, rises
  • remains constant, falls
Show Solution

The Correct Option is D

Solution and Explanation

With a linear consumption function, the Marginal Propensity to Consume (MPC) is invariant, reflecting the constant slope. The Average Propensity to Consume (APC) decreases with rising income, as initial consumption expenditure constitutes a progressively smaller proportion of overall income.
