STATEMENT A: In primary rainbow observer sees red color on the top and violet color on the bottom 

STATEMENT B : In primary rainbow light suffers total internal reflection twice before coming out of water drops 

A rainbow is an optical phenomenon that occurs when sunlight is refracted, or bent, as it passes through water droplets in the air. This bending of light causes the different colors of the spectrum to separate and form a circular arc of colors in the sky.

The main rainbow is created by one entire internal reflection as well as two refractions of white light involving water droplets.
