Answer»

The correct answer is (a) Increases

The EXPLANATION is: The transit frequency is directly PROPORTIONAL to the TRANSCONDUCTANCE of the B.J.T. HENCE, the correct option is increases. Since it hasn’t been mentioned that whether the transconductance has been doubled or not, we cannot CONCLUDE the option “doubles” as an answer.
