A completely submerged body will be stable if ____

11. A completely submerged body will be stable if ____.

  1. Its density is lower than that of the fluid
  2. Its center of gravity is lower than its center of buoyancy
  3. Its center of gravity is above its center of buoyancy
  4. Its weight is greater than the buoyant force

Answer: B) Its center of gravity is lower than its center of buoyancy.

Explanation:

A completely submerged body's center of gravity must be lower than its center of buoyancy in order for it to remain stable. This ensures that any small disturbance will result in a restoring torque that brings the body back to its original position.
