Final answer:
Phenotypic plasticity allows organisms to adapt their phenotype in response to environmental conditions, enabling them to survive and reproduce in diverse and changing environments.
Step-by-step explanation:
The correct statement about phenotypic plasticity is that it allows organisms to adapt to changing environments. Phenotypic plasticity is the ability of an organism to change its phenotype in response to changes in the environment. This means that while the genotype provides a range of possible responses to environmental conditions, the actual physical expression, or phenotype, can vary depending on the specific environmental pressures. This capacity for variation is important for survival and reproduction because it enables organisms to cope with diverse and changing environmental conditions.
