Assertion A normal human eye can clearly see all the objects at the different distance. Reason The human eye has the capacity to suitably adjust the focal length of its lens to a certain extent

1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
3. Assertion is correct but Reason is incorrect
4. Both Assertion and Reason are incorrect

Correct answer: Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

A normal eye can see objects at various distances because it accommodates: the ciliary muscles change the lens shape, altering focal length. This is exactly why the assertion is true and the reason correctly explains it.
