An \( N P N \) transistor is used in common emitter configuration as amplifier with \( 1 \mathrm{k} \Omega \) load
\( \mathrm{P} \) resistance. Signal voltage of \( 10 \mathrm{mV} \) is applied

W across the base-emitter. This produces a \( 3 \mathrm{~mA} \) change in the collector current and \( 15 \mu \mathrm{A} \) change in the base current of the amplifier. The input resistance and voltage gain are:
(1) \( 0.33 \mathrm{k} \Omega, 1.5 \)
(2) \( 0.67 \mathrm{k} \Omega, 300 \)
(3) \( 0.67 \mathrm{k} \Omega, 200 \)
(4) \( 0.33 \mathrm{k} \Omega, 300 \)
