Answer:
C. Flagella
Step-by-step explanation:
Axial filaments are the locomotory organs. They are found in the spirochetes such as Borrelia. Each axial filament is made up of fibrils which are similar to the flagella. These are originated from the periplasmic space of the cell. Periplasmic space is the space between the inner and outer membrane of a cell. It also helps in rotating the cell body. Axial filaments are made up o many endoflagella. It is a special type of filament that arises from endoflagella. Axial filaments help the cell contraction in forward, and backward direction like a screw.
