Answer 1

Answer: (C)

Mycoplasma refers to a genus of bacteria that lack cell wall around their cell membrane. Without a cell wall, they are unaffected by many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. They can be parasitic or saprotrophic. Mycoplasma are the facultative anaerobes, they grow best where there is little or no oxygen.
