The answer is B, a euglena uses a flagella in order to move. Euglena is a one celled organism under the Kingdom Protista. A flagella (or flagellum plural) is a long strand like structure that is located in the front end part (more like a tail in front). It flips to the left and right in order for the organism to move. It is connected to the reservoir, which contains the storage of food for the organism.
