Solution
The correct option is C Arc, Circle
Every rainbow is a circle, but from the ground, usually, only its upper arc can be seen. The rainbow's centre is diametrically opposite to the sun, so more of the rainbow comes into view as the sun approaches the horizon.This means that the largest section of the rainbow when seen from ground is about 50% during sunset or sunrise. From a high viewpoint such as an aircraft, the full-circle rainbow can be seen.
