B)Staphylococcus aureus colonising the nose.
C)Lactobacilli living in the vagina.
D)Escherichia coli living in the bladder.
E)Staphylococcus epidermidis colonising a catheter.

Accepted Answer

Lactobacilli living in the vagina is an example of mutualism as they help maintain the acidic environment essential for preventing the overgrowth of harmful microorganisms. In return, they get a nutrient-rich environment to live in. The other options do not represent mutualism as they involve one organism benefiting at the expense of the other.
