Solution
The correct option is B Pyrrophyta
Pyrrophyta/Dinoflagellates are unicellular protistan algae with complex cell wall structure. The orderly arrangement of cellulosic plates forms armoured plates known as thecae (sing: theca). Thus, the name armoured algae. They have two unequal flagella: pinnate and whiplash. Eugnelophyta is unicellular flagellated eukaryotic protists that lack cell wall but have pellicle which is a semi-rigid proteinaceous structure. They are biflagellates with one very short and one long hairy flagellum. Bascillariophyta, protistian algae, is characterised by the presence of silica-rich cell wall composed of two parts or frustules and absence of flagella.Cyanophyta (Kingdom Monera) is characterised by the presence of peptidoglycan cell wall and absence of flagella. Thus, the correct answer is option B.
