How to decide from a given circuit in which of the four( 1) series-series 2) series-Shunt 3) Shunt- Shunt 4) Shunt - Shunt) category it belong to?

ln the given circuit, if the open loop gain d=10' the feedback configurations and the closed loop gain 4, are o oV, ww 9i 4 (a) series-shunt 4, -9 (b) serices-series, 4,-10 (d)shunt-shunt, 4, -1o (c) serics-shunt, 4, -10
