a. Angular momentum will not be conserved as 
will provide torque about 
. Kinetic energy will remain conserved as tension is perpendicular to velocity and it does not do any work. Obviously, the total mechanical energy also remains conserved
.png)
b. Angular momentum remains conserved as no external torque acts. Mechanical energy and kinetic energy of (rod + sleeve) system will remain the same because no work is done by external forces and there is no dissipating force in the system
c. Angular momentum will remain conserved. Because there is no external force (friction is zero because of ice)
Kinetic energy and mechanical energy will decrease because of work done by internal forces (due to muscles) between the icekaters.
d. Angular momentum will remain conserved, because torque of 
will be zero

will do positive work on the block due to which kinetic energy and mechanical energy of the block will increase
