An increase in income will ?

Correct answer: C. Shift the demand curve

  • A. Lead to a movement along the demand curve
  • B. Shift the supply curve
  • C. Shift the demand curve
  • D. Lead to an extension of demand

Explanation

Income is a demand determinant, so a change in income shifts the entire demand curve rather than causing movement along it. Movement along the curve results from a change in the good's own price.
