Directions : Each of the next items consists of two statements, one labelled 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 :Assertion (A) : The typical common base output characteristics of a bipolar junction transistor remains almost parallel to the voltage axis, but shows very little increase in current with increase in the output voltage.Reason (R) : The short circuit common base current gain (α) of a bipolar transistor increases with increase in the temperature.

• 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
