Direction: Question consists of two statements, one labeled as the 'Assertion (A)' and the other as 'Reason (R)'. Examine these two statements carefully and select the answer to this question using the codes given below:Assertion (A): The short-circuit current gain of a bipolar junction transistor, in common base configuration increases with an increase in the reverse bias collector to base voltage.Reason (R): With an increase in the reverse bias collector to base voltage, the effective base width decreases.

• 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
