Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Bodies radiate heat at all temperatures
Reason R: Rate of radiation of heat is proportional to the fourth power of absolute temperature
In light of the above statements, choose the correct answer from the options given below:

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is NOT the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Hint:

To determine if R is the correct explanation for A, read the assertion, add "because," and then read the reason.
"Bodies radiate heat at all temperatures because the rate of radiation is proportional to the fourth power of temperature."
This statement does not flow logically, confirming that R is not the cause of A.

Answer 1

The Correct Option is B
