A bacterium is capable of withstanding extreme heat, dryness and toxic chemicals. This indicates that it is properly able to form:

1. A thick peptidoglycan wall
2. Endospores
3. Endotoxins
4. Endogenous buds

An endospore is a dormant, tough, non-reproductive structure produced by bacteria. The primary function of most endospores is to ensure the survival of a bacterium through periods of environmental stress.

 

Hence option B is correct

Dear student 

A bacterium is capable of withstanding extreme heat dryness and toxic chemicals. This indicates that it is probably able to form. During unfavourable condition highly resistant signle spore is fomed in the bacterial cell (e.g., Tetanus and anthrax barcteria) which is known as endospore
