Q1:

In a bipolar transistor

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

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

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

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

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

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