(B) Revolution
(C) Sunrise and Sunset
(D) All of the above

Answer 1

Hint :Natural phenomena are the processes that occur with the will of nature and without the interruption of mankind. These phenomena occur at a fixed or in a particular way and mostly are not interfered with by any kind of man made forces or by any living being. Nature is the creator and manager of such phenomena.

Complete Step By Step Answer:
Consider a line that runs through the centre of the Earth and passes through both the North and South Poles. An axis is the name given to this imaginary line. The Earth rotates around its axis in the same way that a top rotates around its spindle. The rotation of the Earth is the name given to this spinning motion. The Earth orbits or revolves around the Sun at the same time it spins on its axis. Revolution is the name given to this movement.
Our solar system's sun remains in its central position. It isn't a rising or setting sun. However, due to the Earth's rotation on its axis, it appears to rise and set. Every 24 hours, it completes one complete turn. It makes a turn to the east.
Thus, all the options mentioned in the question are natural phenomena since they occur naturally without any manmade initiation.
Hence, the correct answer is Option $ (D) $ .

Note :
Different parts of the Earth pass through the sun's light as it spins. Hour by hour, the animation depicts how this appears (for 4 hours). The sun appears to rise in the east as your town turns toward the sun and begins to enter its light. Your town looks to set in the west as the sun's light fades and the darkness sets in.
