Answer:
Option D is correct.
Step-by-step explanation:
When investment increases, aggregate demand increases and income increases. The increase in income induces an increase in consumption expenditure so aggregate demand increases by more than the initial increase in investment.
Aggregate demand is an economic measurement of the total amount of demand for all finished goods and services produced in an economy. Aggregate demand is expressed as the total amount of money exchanged for those goods and services at a specific price level and point in time.
