Correct answer
A. filament, hook, and basal body
Step-by-step solution
Bacterial cells may be motile or non-motile. If motile, they have thin filamentous extensions from their cell wall called flagella. Bacteria show a range in the number and arrangement of flagella . Bacterial flagellum is composed of three parts – filament, hook and basal body . The filament is the longest portion and extends from the cell surface to the outside.
