Which of the following statements are associated with second law of thermodynamics 1. When a system executes a cyclic process, network transfer is equal to net heat transfer. 2. It is impossible to construct an engine, that operating in a cycle will produce no other effect than the extraction of heat from a reservoir and performance of an equivalent amount of work. 3. It is impossible by any procedure, no matter how idealized, to reduce any system the absolute zero of temperature in a finite number of operations 4. It is impossible to construct a device that operating in a cycle will produce no effect other than transfer of heat from a cooler to hotter body. Select the correct answer using the codes given below:

• A. 1, 2 and 4
• B. 2 and 4
• C. 2, 3 and 4
• D. 2 and 3
