Assertion `:` Owls can move freely during night.
Reason `:` They have large number of rods on their retina.

Options

A. If the both assertion and reason are true and the reason is the correct explanation of the assertion
B. If both assertion and reason are true and the reason is not the correct explanation of the assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false statements.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states: "Owls can move freely during the night." This is a true statement. Owls are nocturnal birds, which means they are active during the night and have adaptations that allow them to navigate and hunt in low-light conditions.

**Hint 1:** Consider the adaptations of nocturnal animals that help them thrive in darkness.

### Step 2: Understand the Reason
The reason states: "They have a large number of rods on their retina." This statement is also true. Rods are photoreceptor cells in the retina that are highly sensitive to light and enable vision in dim light conditions. Owls have a high density of rods in their retinas, which allows them to see well at night.

**Hint 2:** Think about the role of rods versus cones in the human eye and how this relates to vision in different lighting conditions.

### Step 3: Connect the Assertion and Reason
Now, we need to determine if the reason correctly explains the assertion. Since the assertion is about owls being able to move freely at night, and the reason explains that this ability is due to the large number of rods in their retina, we can conclude that the reason does indeed explain the assertion.

**Hint 3:** Consider how the structure of the eye contributes to the behavior of animals in different environments.

### Step 4: Conclusion
Both the assertion and the reason are correct, and the reason correctly explains the assertion. Therefore, the correct answer is that both statements are true, and the reason supports the assertion.

**Final Answer:** Both the assertion and reason are correct, and the reason correctly explains the assertion.
