A study found that feather-rich birds were more adaptable to the environment than those of single coat color. Which of the following, if true, would best support the above conclusion? ['Studies have shown that birds used for diverse colors are more likely to succeed in mating, resulting in a higher frequency of mating during the breeding season.', 'Experiments show that birds with many colors and bright colors are more likely to be found by natural enemies, and therefore are more likely to face the pressure of survival than birds with a single color.', 'Research finds that birds with more than one color can quickly evolve into new species, which allows them to survive in a wider environment.', 'Biological research confirms that feather-rich birds often have physiological and behavioral differences, so they have less choice to live in groups than single-colored birds.']
