Correct option (b) Decrease
Explanation:
An object weighs the same in air as well as in water. But, in water an additional buoyant force acts on the ball in a direction opposite to the direction in which the weight of the ball acts. If the weight of the ball acts downwards, buoyant force acts upwards. These two forces work together to make it seem as the object weighs less in water.
