This question was posed to me by my college director while I was bunking the class.

The query is from Solid-State Devices in chapter Introduction to Solid-State Devices of Electric Drives

Answer 1

Right option is (a) β=∝/(1-∝)

To elaborate: The relationship between β and ∝ is β=∝/(1-∝). The current gain is the ratio of the collector current and base current. The value of β is Ic÷IB.
