Solution

The correct option is B The object will be at rest
An object is thrown vertically upward with a non zero velocity. If gravity is turned off at the instant the object reaches the maximum height then it will be at rest due to its inertia. Since at that position of maximum height, its velocity will be zero and the net force on it will be zero also.
