• B. Cell wall
• C. Nucleus
• D. Ribosomes

Answer 1

The correct option is B Cell wall

Mycoplasma is the smallest bacteria. It lacks cell wall around its cell membrane. Due to absence of cell wall, it is resistant to penicillin antibiotics. Penicillin antibiotic inhibits the growth of bacteria by attacking the cell wall. Hence, Mycoplasma is not inhibited by penicillin because it does not have cell wall.

Thus, the correct answer is 'Cell wall.'
