Solution

The correct option is A Auxotroph
The correct answer is A.
Auxotrophs are microorganisms (especially a bacterium or fungus) that are unable to synthesize an essential nutrient because of a gene mutation. This inability of an organism to synthesize a particular organic compound required for its growth is called auxotrophy.
