Question

Directions:

Each of the next fourteen (14) items consists of two statements, one labeled as the ‘Assertion (A)’ and the other as ‘Reason (R)’. You are to examine these two statements carefully and select the answers to these items using the codes given below:

Codes:

(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 

Assertion (A): In a modern coal burning steam generator, the temperature of exiting flue gases from the chimney should be below 100⁰C.         

Reason (R): The lower the temperature of exiting flue gases from the chimney, higher is the heat recovery and therefore higher the efficiency of the steam generator.
