A transistor is operated in common emitter configuration at \( \mathrm{V}_{\mathrm{C}}=2 \mathrm{~V} \) such that a change in the base current from \( 100 \mu \mathrm{A} \) to \( 300 \mu \mathrm{A} \) produces a change in the collector current from \( 10 \mathrm{~mA} \) to \( 20 \mathrm{~mA} \). The current gain is
(a) 50
(b) 75
(c) 100
(d) 25
