Assertion : System of providing name with two compounds is called binomial nomenclature.
Reason : Each name consists first of a specific name and second of a generic name.

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 correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that the system of providing names with two compounds is called binomial nomenclature. This is a correct statement. Binomial nomenclature is indeed the formal system of naming species using two terms.

2. **Understanding the Reason**: The reason provided states that each name consists first of a specific name and second of a generic name. This statement is incorrect. In binomial nomenclature, the first part of the name is the generic name (genus), and the second part is the specific epithet (species).

3. **Evaluating the Truth of Each Statement**:
- The assertion is true because binomial nomenclature is the correct term for the two-part naming system.
- The reason is false because it incorrectly identifies the order of the names; it should be generic name first, followed by the specific epithet.

4. **Conclusion**: Since the assertion is true and the reason is false, the correct answer is that the assertion is true but the reason is false.

### Final Answer:
- Assertion is true but reason is false.
