The output of the op-amp in a Band Pass Filter (BPF) circuit when given a square wave input will be a sine wave.

Here's why:

1. A Band Pass Filter (BPF) is designed to pass signals within a certain frequency range and reject signals outside this range.

2. When a square wave is input into a BPF, the BPF will filter out the higher harmonics of the square wave.

3. A square wave can be thought of as a fundamental frequency sine wave (the first harmonic) plus an infinite series of odd-harmonic sine waves.

4. The BPF will allow the fundamental frequency to pass through while attenuating the higher frequency harmonics.

5. The result is that the output will look more like a sine wave, which is the fundamental frequency component of the square wave.

So, the answer is a. Sine Wave.
