- AThe object will begin moving toward the left, and it will accelerate at a greater rate than before
- BThe object will continue moving toward the right, but it will accelerate at a greater rate.
- CThe object will continue moving toward the right, but it will move at a slower speed.
- DThe object will experience acceleration toward the left
