Detailed Solution

Concept- To determine the resolving power of the human eye, we must first define resolving power. The human eye's sight is limited to a certain distance. This concept will be quite beneficial in answering the question.
We know that the normal pupil size of a human being is

. . This measurement establishes a minimum resolution of around

. to 2prime. When we wish to bring little objects closer to our eyes, we want to be able to see them clearly. However, it is frequently seen that after a certain distance, the particles become unclear regardless of how close they are to our sight. This indicates that a comfortable viewing distance exists. This distance is approximately computed as

.
As a result, Option A is the proper response to the question.
Additional Information: The most significant feature of an optical system is the resolving power of a microscope. This is significant because it influences the ability to detect small details of a certain specimen. When we refer to a microscope's or telescope's resolving power, we imply its capacity to discriminate between two pictures when they are near together.
Hence, the correct answer is option 1.
