C no internal refraction
D either one or two internal refractions before emerging out of the drop

Correct Answer: one internal refractions before emerging out of the drop

Primary rainbow is formed when light suffers one internal refractions before emerging out of the drop. In a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.
