Explanation:

Lipopolysaccharide (LPS) in Gram - negative bacteria has three main components: O antigen, Lipid A, and core polysaccharide. Lipid A is the toxic part (endotoxin) that can trigger immune responses and cause symptoms during infection. The O antigen is more for serotyping, and the core polysaccharide has a structural role rather than being the toxic component.

Answer:

B. Lipid A
