Correct answer
A. A - 4, B - 1, C - 3, D - 2
Step-by-step solution
A - 4: Chrysophytes include diatoms and golden algae (desmids). They are microscopic, planktonic, and have silica-embedded cell walls that are indestructible. B - 1: Dinoflagellates are mostly marine and photosynthetic, with cellulose plates and two flagella. They can cause red tides due to rapid multiplication and produce toxins that may harm marine life. C - 3: Euglenoids are primarily freshwater organisms with a flexible body due to the presence of a pellicle. They are photosynthetic in light but can act as hete
