Moran · Answer 1

Option (2)

Explanation:

The weight of an object is always more at the sea level than at the base of the ocean floor. The water always forces an upward thrust to an object, as a result of which the weight of the object gets reduced by a certain amount. This property of water generating an upward force is known as the the buoyancy.

Thus, if an object weighs 25 grams at the ocean floor, then at the mean sea level, the weight is slightly more than 25 grams.

Hence, the correct answer is option (2).
