Question

Assertion (A): If an alcohol and a mercury thermometer read exactly 0⁰C at the ice point and 100⁰C at the steam point and the distance between the two points is divided into 100 equal parts in both thermometers, the two thermometers will give exactly the same reading at 50⁰C.

Reason (R): temperature scales are arbitrary.                                  

(a) Both A and R are individually true and R is the correct explanation of A

(b) Both A and R are individually 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
