Answer:

d. A change in the fitness of non-poisonous butterflies as a result of the numbers of poisonous ones in the population

Explanation:

Frequency dependant selection is a function of frequency in a population i-e the fitness of a phenotype declines if it becomes too common in a population.

Selection can favour whichever phenotype is less common in a population (as mentioned in the given scenario , the change in the fitness of the non-poisonous butterflies as a result of numbers of poisonous ones in the populations )

Hence option d. A change in the fitness of non-poisonous butterflies as a result of the numbers of poisonous ones in the population IS THE RIGHT ANSWER.
