Low pass filter succeeded by high pass filter in the above figure if we observe and hence according to their responses we get band stop filter's response..so ans is d

Low pass filter circuit is parallel to high pass filter circuit therefore this circuit behave as band stop filter.

It's very easy to say that it should be a band stop filter.

@Mahapatra.
How you can say so easily without giving any explanation.

In this circuit had 2 capacitor that is input and output. That is called cc. So it works band stop filter.

I think it is a narrow band pass filter. Check chapter 7 of the book 'Op-Amps and linear integrated circuits' by Ramakant A Gayakwad.

If capacitor is connected to ground is called low pass filter. If resistor is connected to gnd is called high pass filter.

By observing the capacitor actions at lower frequency and higher frequency the given circuit is band pass filter.

I too agree with @Madhavi. It seems to be band pass filter by analyising the circuit at f=0 and f=infinity.
