What is the difference between a facultative anaerobe, anaerotolerant anaerobe, and an obligate anaerobe? which one iscorrect?

a-Obligate anaerobes require an oxygen-free environment tosurvive, but aerotolerant anaerobes just grow better in anoxygen-free environment than with oxygen. Facultative anaerobesgrow equally well in either environment.

b-Aerotolerant anaerobes do equally well with or without oxygen,but facultative anaerobes do better without oxygen than with it.Obligate anaerobes require oxygen.

c-Obligate anaerobes require an oxygen-free environment tosurvive, but aerotolerant anaerobes grow better in an environmentwith oxygen than without it. Facultative anaerobes grow equallywell in either environment.

d-Facultative anaerobes can use oxygen, producing more ATP thanwithout it. Aerotolerant anaerobes are unaffected by oxygen, butcannot use it. Obligate anaerobes require an oxygen-freeenvironment to survive.
