Assertion: The efficiency of a carnot engine cannot be `100%`. Reason:

1.	Assertion: The efficiency of a carnot engine cannot be `100%`. Reason: This is because sink of heat engine cannot be maintained at `0 K`.A. If both, Assertion and Reason are true and Reason is the correct explanation of the Asserrion.B. If both,Assertion and Reason are true but Reason is not a correct explanation of the Assertion.C. If Assertion is true but the Reason is false.D. If both, Assertion and Reason are false.
Answer» Correct Answer - A Here, both assertion and reason are true, and reason is correct explanation of assertion As efficiency, `eta= 1-(T_(2))/(T_(1)), T_(2)!= 0, :. eta!=1`
