The right answer is B. peptidoglycans.

Peptidoglycan (or murine, or mucocomplex, or mucopeptide) is a component of the bacterial wall maintaining the shape of cells and providing mechanical protection against osmotic pressure. It forms a thin layer in Gram-negative bacteria and a thick layer in Gram-positive bacteria.

It consists of a carbohydrate moiety (= polysaccharide) and a peptide moiety. The polysaccharide is a glycosaminopeptide polymer wherein N-acetylglucosamine (NAG) and N-acetyl-muramic acid (NAM) are linked by beta (1-4) osidic bonds. This bond can be cut off by lysozyme. NAM is a specific compound of bacterial walls. Two polysaccharides are linked by peptide bridges at the level of the NAM, formed by different amino acids: D-alanine, L-alanine, glutamic acid, L-lysine, diaminopimelic acid (lysine analog). Amino acids D are specific for the bacterial wall, they are never found elsewhere.

Vanyuwa [196]

Answer;

-inhibition of peptidoglycan synthesis

-inhibition of fimbriae synthesis

-interfering with translation at 70s ribosomes

Explanation;

- Selective toxicity refers to the ability of the drug to targets sites that are relative specific to the microorganism responsible for infection. Sometimes these sites are unique to the microorganism or simply more essential to survival of the microorganism than to the host.

-Antibacterial action generally falls within one of four mechanisms, three of which involve the inhibition or regulation of enzymes involved in cell wall biosynthesis, nucleic acid metabolism and repair, or protein synthesis, respectively. The fourth mechanism involves the disruption of membrane structure.
