Part B. To what color does this correspond?

a green

b) blue

c) red

d) orange

Interference:

Interference is the phenomenon that occurs when waves of the same frequency meet and superimpose. There are two types of interference which are the constructive and destructive interference. When the interference results to a wave of higher amplitudes than each of the constituent waves, the process is referred to as constructive interference. Otherwise, it is destructive interference.
