The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Organism**: The question mentions "Gonyaulax," which is a type of dinoflagellate. Dinoflagellates are a group of protists that are known for their ability to photosynthesize and can be found in marine environments. 2. **Understand the Phenomenon**: The rapid multiplication of Gonyaulax leads to a significant increase in their population, which can color the water red. This phenomenon is a result of the high concentration of these organisms in a specific area. 3. **Define the Term**: The rapid increase in the population of these algae is referred to as an "algal bloom." When this bloom is specifically caused by dinoflagellates like Gonyaulax, it is commonly known as "red tide." 4. **Recognize the Effects**: Red tide can produce toxins, such as saxitoxin, which can be harmful to marine life and even humans. This toxicity can lead to neurological issues and can be fatal to various marine organisms. 5. **Choose the Correct Answer**: From the options provided, the correct term for the phenomenon where Gonyaulax causes the sea to appear red is "red tide." **Final Answer**: The phenomenon is called **red tide**. ---
