Solution
The correct option is A Peritrichous
Based on the number and the position of the flagella, bacteria can be divided into the following kinds: Monotrichous, lophotrichous, amphitrichous, peritrichous, and atrichous. Bacteria that have a single flagella at one end of their body, like Vibrio cholerae, are called monotrichous. Those having several flagella at one end, like Pseudomonas, are called lophotrichous. Those having a single flagella on both ends, like Rhodospirillum rubrum, are called amphitrichous. Those having several flagella attached all around the organism, like E.coli, are called peritrichous. And finally, those without any flagella, like Lactobacillus, are called atrichous.
