Solution
The correct option is B S-layer
In gram-positive bacteria, the S-layer is attached to the peptidoglycan layer. The S-layer may protect the cell from aggressions such as phagocytosis, harmful enzymes, etc. It also allows bacteria to adhere to host cells or other environmental surfaces and to mantain shape and envelope rigidity.
