Chemistry · Some Basic Concepts of Chemistry

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Negative temperature values are possible on the Celsius scale, but temperatures below \( 0\text{ K} \) are not possible on the Kelvin scale. Reason (R): The Kelvin temperature scale has degrees identical in magnitude to the Fahrenheit scale. In the light of the above statements, choose the correct answer from the options given below:

1. A
   Both (A) and (R) are true and (R) is the correct explanation of (A).
2. B
   Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. C
   (A) is true but (R) is false.
4. D
   (A) is false but (R) is true.
