Quizplus · Accepted Answer

Auxotrophs have lost the ability to grow on minimal medium due to a mutation which has disrupted their ability to synthesize a nutrient required for growth. Prototrophs, on the other hand, are able to grow on minimal medium as they can synthesize all the nutrients they need. Mutants and adaptation are general terms that may or may not be related to the loss of ability to grow on minimal medium. Therefore, option D best explains the situation.
