Answer 1

Right answer is (c) band pass filter To explain I would say: A band pass filter passes frequencies between two designated cut-off frequencies and attenuates all other frequencies. A band pass filter has two cut-off frequencies and will have the pass band f2-f1; f1 is the lower cut-off frequency, f2 is the upper cut-off frequency.
