The red ray is refracted less than the blue ray, causing it to bend at a smaller angle and emerge higher in the sky. This means that the blue ray lies below the red ray, making choice C the correct answer. Additionally, the blue ray is more nearly horizontal than the red ray because it is refracted more and emerges at a steeper angle from the raindrop.
