(Refer to below statements A, B, and C to answer the question) A) Seals would use air in their lungs to catch prey that was often limited. This resulted in larger lungs each generation. Therefore seals could hold their breath longer to catch preys that were growing less available. B) Some seals were born with chance mutations that enabled them to hold their breaths longer. This mutation helped them to survive and pass on their traits more successfully to future generations. C) Individual seals learned how to hold their breath longer. Seals that learned this adaptive behavior passed it on to their offspring.
