Answer:
The correct answer is option D.
Step-by-step explanation:
A reduction in consumer confidence will cause the IS curve to move leftwards. The IS curve is short for the investment savings curve. It shows the equilibrium in the goods market. It shows different combinations of interest rates and income where the goods market is in equilibrium.
A change in consumer spending causes a shift in the IS curve. A reduction in consumer confidence will cause consumers to spend less. This reduction in consumer spending will further cause the IS curve to shift to the left.
