Correct answer
A. A - 2, B - 1, C - 3, D - 4
Step-by-step solution
A - 2: Chrysophytes, such as diatoms, have silica-embedded cell walls that form diatomaceous earth upon their accumulation over billions of years. B - 1: Dinoflagellates can undergo rapid multiplication causing "red tides", especially red dinoflagellates like Gonyaulax. C - 3: Euglenoids have a unique protein-rich layer called pellicle which provides flexibility to their bodies. D - 4: Slime Moulds form an aggregation called plasmodium during their life cycle and produce spores in unfavorable conditions, which are
