Match the following type of bacterium with examples.
A) Salmonella is atrichous because it does not have any flagella on its surface.
B) Vibrio is monotrichous because it only has one flagellum used for its movement.
C) Lactobacillus is peritrichous because the bacillus is surrounded by numerous flagella around it.
So, the correct combination is A-2, B-3, C-1.
