The correct answer is b) π (pi).

At the first minimum of the diffraction pattern, the phase difference between the rays coming from the two edges of the slit is π (pi) radians. This is because at the first minimum, the waves from the two edges of the slit interfere destructively, resulting in a minimum intensity. In order for this destructive interference to occur, there must be a phase difference of π (pi) between the two waves.
