The Polaris remains below horizon at

Solution (By Examveda Team)

The correct answer is Option D: 5° S latitude.
Here's why:
Polaris, also known as the North Star, is located very close to the North Celestial Pole.
The altitude of the North Celestial Pole above the horizon is equal to the observer's latitude in the Northern Hemisphere.
If you are at the Equator (0° latitude), Polaris will be right on the horizon.
As you move northward, Polaris appears higher and higher in the sky.
However, Polaris can only be seen from locations in the Northern Hemisphere or very close to the equator.
If you are in the Southern Hemisphere, Polaris will be below the horizon.
Since 5° S latitude is in the Southern Hemisphere, Polaris will be below the horizon there.
At 10° N and 50° N latitude, Polaris will be visible above the horizon.
At the Equator, Polaris will be on the horizon.
