Correct answer
Bangular momentum
Step-by-step explanation
Let it be assume that in "free space" not only the acceleration due to gravity it acting but al there are no external torque acting but also there are no external torque acting on the sphere. If due to internal changes in the system, the radius has increased, then the law of the conservation of angular momentum holds good.
