Answer

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

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Drugs classification based on pharmacological effect is useful for doctors."
- This means that categorizing drugs according to how they affect the body (pharmacological effects) helps doctors in their practice.

2. **Understanding the Reason**:
- The reason states that "It provides the whole range of drugs available for the treatment of a particular type of problem."
- This implies that by classifying drugs based on their effects, doctors can easily identify and choose from a variety of drugs that can treat specific medical issues.

3. **Analyzing the Relationship**:
- The assertion is true because drug classification does indeed help doctors understand and utilize different medications effectively.
- The reason is also true because having a classification system allows doctors to see all available treatment options for a specific condition.

4. **Conclusion**:
- Since both the assertion and the reason are true, and the reason correctly explains why the assertion is true, we can conclude that the statement is correct.

5. **Choosing the Correct Option**:
- Based on the analysis, the correct choice would be the one that states both the assertion and reason are true, and the reason supports the assertion.

### Final Answer:
The correct option is (1) - Both Assertion and Reason are true, and the Reason is a correct explanation of the Assertion.
