pls mark me as brainliest

Explanation:

Answer 2

10 km is the distance at which human eyes can see things properly. Hence, the correct option is (d).

The proper justification of the answer is :

• We can also see things at the infinity distance as our eyes are able to see the astronomical objects i.e., stars, moon, sun etc.
• So the ability to see things is set to infinity because of the the far point. The far point is the maximum point at which the ability of eye to see objects are clear up to the ultimate point.
• But when it comes on seeing things clearly then only 10 km of distance is appropriate for the human eye.
