A ship is made of iron but still it floats in water. This is because of its shape. A ship is hollow in the middle. When it is in water, the entire volume of the ship, including the hollow portion displaces water to make space for itself. The volume of water displaced is much more than the volume of iron in the ship. Therefore, the ship floats in water.
Which of these rules can be deduced from the above given passage?

A If the upthrust is more than the weight, the body sinks in water.
B If the weight is more than the upthrust, the body floats in water.
C If the upthrust is less than the weight, the body floats in water.
D If the weight is more than the upthrust, the body sinks in water.
