Assertion: The temperature of the surface of the sun is approximately `6000 K`. If we take a big lens and focus the sun rays, we can produce a temperature at `8000 K`
Reason: This highest temperature can be produced according to second law of thermodynamics.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false

Answer

D

Explanation

According to second law of thermodynamics, this is not possible to transfer heat from a body at lower temperature to a body at higher temperature without the aid of an external agent. Since, the given information produces a contradiction in second law of thermodynamics, therefore it is not possible to produce temperature of 8000 K by collecting the sun rays with a lens.
