Answer:
The correct answer is C. can propel bacteria toward a food source.
Explanation:
Bacterial flagella is a thin, long whip-like appendage which is made up of a protein called flagellin and is attached to the bacterial cell. The flagella play an important role in the movement of bacteria from one place to another in its environment.
It helps bacteria to propel bacteria towards the food source and getting their food. The movement of flagella is powered by protein motive force which is present in the bacterial plasma membrane. Therefore the correct answer is C. can propel bacteria toward a food source.
