  • B.Outer Membrane
  • C.Cytoplasmic Membrane

Answer: B

Correct answer: Outer Membrane

The gram-negative basal body has four rings, and the letters name where each sits: L in the outer membrane (L for lipopolysaccharide), P in the peptidoglycan, and S and M at the cytoplasmic membrane. Gram-positive cells, having no outer membrane, have only the S and M rings.
