The correct option is
D Staphylococcus aureusA super bug is a bacteria which is resistant to antibiotics.
Staphylococcus aureus is a super bug because it is resistant antibiotic known as methicillin. Methicillin, a β-lactam antibiotic, acts by inhibiting penicillin-binding proteins (PBPs) that are involved in the synthesis of peptidoglycan, an essential mesh-like polymer that surrounds the cell.
So, the correct answer is 'Staphylococcus aureus'.
