The correct answer is C) only on amino acid supplemented media.
To understand why, let's break down the options:
A) Auxotrophs are organisms that have a mutation in a gene that makes them unable to synthesize a particular nutrient that is essential for their growth. Therefore, they cannot grow on minimal media, which typically lacks specific nutrients.
B) Auxotrophs may or may not require sunlight for growth, but sunlight is not directly related to their nutritional requirements. So, they are not restricted to growing only with sunlight (although many organisms do require sunlight for photosynthesis).
C) This statement is correct. Auxotrophs require the addition of specific amino acids to the growth media because they are unable to produce these essential building blocks themselves.
D) Similarly to C, auxotrophs need the addition of specific vitamins to the growth media if they cannot synthesize them. However, this applies to only some auxotrophs, not all of them.
E) Auxotrophs cannot grow on any media because they lack the ability to produce certain essential nutrients. They require the addition of specific components to the growth media to support their growth.
Therefore, the correct option is C) only on amino acid supplemented media.
