Adaptation is a crucial concept in biology that pertains to how species adjust to their environments over time. When environmental challenges arise—such as changes in climate, availability of food, or presence of predators—species that have traits enabling them to cope with these challenges are more likely to survive and reproduce.

The correct answer indicates that adaptation increases a species' chance of survival and reproduction. This is because through the process of natural selection, advantageous traits become more common in a population. For example, a species that develops a thicker fur coat in response to colder temperatures can better withstand the cold, leading to higher survival rates. Likewise, traits such as faster speeds or better camouflage can enhance an organism's ability to find food or evade predators, further promoting reproductive success.

In summary, adaptations enhance a species' fitness in their specific environment, allowing them to thrive despite challenges. This concept is fundamental to understanding evolution and the diversity of life on Earth.
