Solution
The correct option is B second
The second law of thermodynamics states that when energy change from one form to another form, entropy in a closed system increases.In other words it can be stated as,It is impossible to construct a device which produces no other effect than transfer of heat from lower temperature body to higher temperature body.Hence it is clear that second law of thermodynamics leads to the interference that is difficult to convert whole of heat into work.
