Answer:

b. The path one of the rays must travel is 1/2 a wavelength shorter than the path of the other ray.

Explanation:

Both waves have the same wavelength and frequency and they have to travel to the same point, however the path traveled is different, so one of the rays will need more wavelengths to travel more distance which makes the rays to be out of phase, so the answer is

The path one of the rays must travel is 1/2 a wavelength shorter than the path of the other ray.
