An NPN transistor is used in common emitter configuration as an amplifier with 1 kΩ load resistance. Signal voltage of 10 mV is applied across the base-emitter. The produces a 3 mA change in the collector current and 15μA change in the base current of the amplifier. The input resistance and voltage gain are
(1) 0.67 kΩ, 300
(2) 0.67 kΩ, 200
(3) 0.33 kΩ, 1.5
(4) 0.33 kΩ, 300
