Solution

A- 1,2,5
B- 2
C-4
D-4
The energy of a system will never increase when capacitor gets charged, gas is compared by pushing the piston and loop placed in a time varying magnetic field perpendicular to its plane. Mechanical energy is converted into another energy when gas B. Compressed by pushing a piston due to random motion of molecules. Internal energy is converted into mechanical energy during fission process.
During nuclear fission a heavier nucleus splits into two daughter nuclei and thus the mass get reduced
