Explanation

### Step-by-Step Text Solution:

1. **Understanding the Assertion**:
- The assertion states that "Horticulture is a branch of agriculture that deals with the production of vegetables, fruits, flowers, and decorative flowers."
- This means that horticulture focuses on cultivating various types of plants, especially those that are consumed or used for decoration.

2. **Understanding the Reason**:
- The reason provided is "Horticulture is similar to agriculture in many ways, but it is usually carried out on a smaller scale."
- This indicates that while horticulture shares similarities with general agriculture, it typically involves smaller plots of land and is often more specialized.

3. **Evaluating the Assertion and Reason**:
- Both the assertion and the reason are true statements. Horticulture indeed involves the production of various plants, and it is generally practiced on a smaller scale compared to traditional agriculture.

4. **Analyzing the Relationship**:
- The assertion describes what horticulture is, while the reason explains a characteristic of horticulture. However, the reason does not directly explain the assertion. It provides additional information but does not clarify or support the assertion itself.

5. **Conclusion**:
- Since both the assertion and the reason are correct, but the reason does not provide a correct explanation for the assertion, the correct conclusion is that both statements are true, but the reason is not the correct explanation of the assertion.

### Final Answer:
- The correct option is that both the assertion and the reason are correct, but the reason is not a correct explanation of the assertion.
