Show answer and explanation

Correct answer: (A) Staphylococcus aureus

Explanation

Cholera, pathogenic E. coli infections and typhoid are standard enteric/waterborne examples. S. aureus is chiefly associated here with toxin-mediated food poisoning rather than this enteric-pathogen group. The intended exception is A; this does not imply that it cannot cause foodborne illness.
