To solve the question regarding the assertion and reason about red tide and Gonyaulax, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Assertion**: The assertion states that "Red tide is caused by Gonyaulax." - This is a statement that needs to be evaluated for its truthfulness. 2. **Identify the Reason**: The reason provided is "Gonyaulax is a marine dinoflagellate that accumulates in the sea to provide color and cause the red tide." - This statement explains why Gonyaulax is associated with red tide. 3. **Evaluate the Assertion**: - Red tide is indeed caused by certain species of dinoflagellates, including Gonyaulax. - Therefore, the assertion is **true**. 4. **Evaluate the Reason**: - Gonyaulax is classified as a marine dinoflagellate, and it does accumulate in water bodies, leading to the phenomenon known as red tide due to its rapid multiplication. - Hence, the reason is also **true**. 5. **Determine the Relationship**: - The reason provided explains the assertion correctly. Gonyaulax being a marine dinoflagellate is directly related to its role in causing red tide. 6. **Choose the Correct Response**: - Since both the assertion and reason are true, and the reason provides a correct explanation for the assertion, the correct response is: - **Both assertion and reason are true, and reason is a correct explanation of the assertion.** ### Final Answer: Both assertion and reason are true, and reason is a correct explanation of the assertion. ---
