what is occurring when two waves traveling along the same medium meet and cancel each other out?\no…

Brief Explanations:

When two waves meet and cancel each other out, it's destructive interference. In destructive interference, the peaks of one wave align with the troughs of the other, resulting in a net zero - amplitude wave at that point. Constructive interference is when waves add up to a larger amplitude. Reflection is the bouncing back of a wave from a boundary, and refraction is the bending of a wave as it passes from one medium to another.

Answer:

A. destructive interference
