Answer 1

Answer:

The correct answer will be- option-B

Explanation:

Endotoxin is a pyrogen which causes fever in humans and animals. The endotoxin is the lipopolysaccharide portion of the exterior cell wall of the gram-negative bacteria which consists of lipid A portion, O-antigen, disaccharide phosphate and the core polysaccharides.

The lipid A portion of the lipopolysaccharide is the cause of the endotoxin nature which is sensed by the immune cells of humans and other animals as an antigen which causes fever.

Since endotoxin is found in the lipopolysaccharide of the gram-negative bacteria, therefore, is an indication of the gram-negative bacteria.
