(b) Statement I is true; Statement II is true: Statement II is not the correct explanation of Statement I.

(d) Statement I is false; Statement II is true.

Statement I : There is a natural asymmetry between converting work to heat and converting heat to work. 

Statement II : No process is possible in which the sole result in the absorption of heat from a reservoir and its complete conversion into work.

Answer 1

(a) Statement I is true; Statement II is true; Statement II is a correct explanation of Statement I.

(b) Statement I is true; Statement II is true: Statement II is not the correct explanation of Statement I.

Explanation:

There is natural asymmetry between converting work to heat and converting heat to work because of the lapse of energy in this process which has been generalised in the form of second law of thermodynamics (Statement-II).
