Final answer:

A Gram-positive bacterial cell has a thick peptidoglycan layer embedded with teichoic acids, which stabilize the cell wall and assist in infection processes.

Step-by-step explanation:

A Gram-positive bacterial cell has a thick layer of peptidoglycan and contains unique polyalcohols called teichoic acids. The correct answer to the question is C) Teichoic acids.

Peptidoglycan is composed of polysaccharide chains that are cross-linked by unusual peptides, and in Gram-positive bacteria, these peptidoglycan layers are commonly embedded with teichoic acids, which are thought to stabilize the cell wall by increasing its rigidity.

Teichoic acids also play a key role in the pathogenicity of Gram-positive bacteria, by helping them to bind to host cell surfaces, thereby enhancing their ability to cause infection.
