Assertion : Over-exploitation of a species reduces the size of its population eventually leading to its extinction.
Reason : Steller's sea cow is a large, herbivorous, terrestrial mammal which is on the verge of extinction due to over exploitation.
(a) If both assertion and reason are true and reason is the correct explanation of assertion.
(b) If both assertion and reason are true but reason is not the correct explanation of assertion.
(c) If assertion is true but reason is false.
(d) If both assertion and reason are false.

Options

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

Explanation

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

### Step 1: Analyze the Assertion
The assertion states that "Over-exploitation of a species reduces the size of its population eventually leading to its extinction."
- This statement is true. Over-exploitation, which refers to the excessive harvesting of a species, can lead to a significant decline in its population size, ultimately resulting in extinction.

### Step 2: Analyze the Reason
The reason states that "Steller's sea cow is a large, herbivorous, terrestrial mammal which is on the verge of extinction due to over-exploitation."
- This statement is false. The Steller's sea cow was indeed a large herbivorous mammal, but it is not on the verge of extinction; it has already become extinct. The species was discovered in 1741 and went extinct by 1768 due to over-exploitation for its meat, skin, and fat.

### Step 3: Determine the Relationship Between Assertion and Reason
- Since the assertion is true and the reason is false, we conclude that the correct option is (c): "If assertion is true but reason is false."

### Final Answer
(c) If assertion is true but reason is false.
