An NPN transistor is used in common emitter configuration as an amplifier with 1 k
load resistance. Signal voltage of 10 mV is applied across the base−emitter. This produces a 3 mA change in the collector current and 15 
A change in the base current of the amplifier. The input resistance and voltage gain are :
(a)
0.33 k
, 1.5
(b)
0.33 k
, 300
(c)
0.67 k
,200
(d)
0.67 k
