Tube B shows the expected growth pattern for a facultative anaerobe. This is because it has growth throughout the tube, but with more growth at the top where there is access to some oxygen. Facultative anaerobes can grow in the presence or absence of oxygen, but will usually grow better in the presence of oxygen. The other tubes either show no growth (A, D) or growth only in the absence of oxygen (C, E), which is not characteristic of a facultative anaerobe.
