When a transistor amplifier having current gain of `75` is given an input signal, `V_(I) = 2 sin (157 t + pi//2)`, the output signal is found to be `V_(o) = 200 sin(157 t + 3pi//2)`. The transistor is connected as :
A. common base amplifier
B. common emitter amplifier
C. common collector amplifier
D. feed back amplifier
