<u>Option-(A): </u>A new moon is quite near the Sun in the sky.
Explanation:
- While the position of the new moon inside our sky has such an orientation that we are not able to see or observe the actual position and shape of the new moon.
- As the path or revolution is much more elliptical then we can imagine, for the moon there are certain position of motion inside the celestial space that for some times it looks for different then the other and such position generates the concept of a new moon.

An Earth revolution is a trip around the sun in a closed path (relative to the sun).
The path is very nearly an ellipse with the sun at one focus, and a little less nearly a circle with the sun at the center.
One complete revolution takes roughly 365.24 days, and at that point, the Earth immediately begins another one.
We have a special word that we use to refer to that special period of time. In English, it's called a "year".

H = V²/(2g) + 0.00045 = 0.0597 + 0.00045 = 0.06014 m = 6.014 cm </span>
