Solution

The correct option is B Prototroph
  • Prototroph is the nutritionally wild strain that is able to grow in the minimal medium and does not require additional nutrients in the medium.
  • Auxotrophs are microorganisms that are unable to synthesize essential nutrients due to gene mutation.
  • Phenotype is the kind of organism produced by the reaction of a given genotype to the environment.
  • An autotroph is an organism that can generate its own food using light, water, carbon dioxide, or other chemicals.
