Answer: Option (B) is the correct answer.
Step-by-step explanation:
We cannot find the volume of an irregular solid because we can never measure the volume of curves that are present in an irregularly shaped object.
Therefore, we tend to place this irregular object in a beaker of water so that the volume of water displaced by it will actually show us the volume of object itself.
Hence, we can conclude that water displacement is an effective way of measuring the volume of an irregular solid there is no way of finding the volume of an irregular shape.
