When predators are not present, tadpoles with large tails have low fitness and tadpoles with small tails have high fitness. Under which of the following situations would the plastic genotype be favored over other genotypes?
I. if all environments have predators
II. if no environments have predators
III. if environments with predators are as common as environments without predators

• A) situation I
• B) situation II
• C) situation III
• D) situations I and II
