Consider the following statements regarding the Second Law of Thermodynamics: 1. The Kelvin-Planck statement asserts that it is impossible to construct a heat engine operating in a cycle that extracts heat from a single reservoir and performs an equivalent amount of work. 2. The Clausius statement asserts that heat cannot spontaneously flow from a cooler body to a warmer body without external work. 3. The Second Law implies that the total entropy of an isolated system can never decrease over time. Which of the statements given above are correct?

Options:

• A: 1 and 2 only
• B: 2 and 3 only
• C: 1, 2 and 3
• D: 1 and 3 only
