In a bipolar transistor

recombination in base regions of both n-p-n and p-n-p transistor is low

recombination in base regions of both n-p-n and p-n-p transistors is high

recombination in base region of n-p-n transistor is low but that in p-n-p transistor is high

recombination in base region of p-n-p transistor is low but that in n-p-n transistor is high

Correct Answer : Option (A) : recombination in base regions of both n-p-n and p-n-p transistor is low

Explanation : Base is very thin and therefore recombination is minimum in both p-n-p and n-p-n transistors.
