Solution

The correct option is A Toxins
Exotoxins are proteins that are synthesised and secreted by bacteria into surrounding medium. These are toxic and antigenic and can be neutralised by antitoxins. Antibiotics are medicines that kill or inhibit the growth of bacteria. Antitoxins are an antibody, that neutralises the specific toxin. Auxins are plant hormones which help in cell division and differentiation.
So, the correct answer is option A.
