Explanation
The correct answer is A. Red tides are phenomenon where estuarine or coastal waters change color due to the rapid multiplication of certain microscopic algae, primarily pigmented dinoflagellates. These organisms contain photosynthetic pigments that can turn the water red, brown, or pink. These blooms can be harmful because they may deplete oxygen in the water or release toxins that are dangerous to marine life and humans. The terms sea tides, black tides, and sea flowers are not standard scientific descriptors for these specific algal blooms.
