Superposition, Coherence & Intensity

The phase difference between two waves giving rise to dark fringe in Young's double slit experiment is ( n is the integer)

Show answer and solution

Answer: (c)

Destructive interference (dark fringe) needs a phase difference that is an odd multiple of $\pi$ .
Odd multiple of $\pi$ is written $(2n-1)\pi$ for integer $n$ .
So the answer is (c) $(2n-1)\pi$ .
