According to me 2 op-amp is required.

Well, here the second term, [Rf/R3xRf/R1] contains two gains multiplied, so it is very obvious that two systems have to be cascaded [basic control system] and the first term can be easily provided by using the concept of superposition.

So, B seems to be right.
