Answer:

Option C. Leftward by $40 billion at each price level

The shift would be leftward because the decrease in investment results the decrease in the aggregate demand which will decrease the aggregate demand by decrease in investment divided by multiplier 0.5, which gives $40 billion decrease in aggregate demand.
