(a)
a. when the sphere rolls on the rough surface, its angular momentum about contact point 
remains constant because torque of friction 
about this point is zero
.png)
b. Here no friction will on the sphere. So here everything will remain the same
c. here also no friction will act, so everything will remain the same
d. Here KE will increase. Potential energy will decrease but the total mechanical energy will remain constant. Angular momentum will not be conserved, because 
will provide the torque about contact point
