Band Reject filter to reject frequencies between f1 & f2 (f2 > f1) can be constructed by _______.

• A. Connecting LPF of fc = f1 followed by HPF of fc = f2 in series
• B. Connecting LPF of fc = f2 followed by HPF of fc = f1 in series
• C. Connecting LPF of fc = f1 and HPF of fc = f2 in parallel
• D. Connecting inputs of both LPF of fc = f1 and HPF of fc = f2 and then summing their outputs
