Assertion : A normal human eye can clearly see all the objects beyond a certain minimum distance.
Reason : The human eye has the capacity to suitable adjust the focal length of its lens to a certain extent.

Options

A. If both, Assertion and Reason are true and the Reason is the correct explaination of the Assertion.
B. If both, Assertion and Reason are true but Reason is not a correct explaination of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both, Assertion and Reason are false.

Explanation

To analyze the given assertion and reason, we can break it down step by step:

### Step 1: Understand the Assertion
The assertion states that "A normal human eye can clearly see all the objects beyond a certain minimum distance."
- This is true because the human eye has a specific range of vision. Objects that are too close (within the near point, typically around 25 cm for a normal eye) cannot be seen clearly, while objects beyond this distance can be focused clearly.

### Step 2: Understand the Reason
The reason states that "The human eye has the capacity to suitably adjust the focal length of its lens to a certain extent."
- This is also true. The eye's lens can change its shape to focus on objects at various distances. This ability is known as accommodation. The lens becomes thicker to focus on nearby objects and thinner for distant objects.

### Step 3: Evaluate the Relationship
Now we need to evaluate whether the reason correctly explains the assertion.
- Since the ability of the eye to adjust its focal length (accommodation) allows it to see objects clearly beyond a certain minimum distance, the reason supports the assertion.

### Step 4: Conclusion
Both the assertion and the reason are true, and the reason is indeed a correct explanation of the assertion. Therefore, the correct answer to the question is that both statements are true, and the reason is the correct explanation for the assertion.

### Final Answer
The answer is A: Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
