evolution is
the adaptation of organisms to aquatic environments.
a random and immediate genetic change after an individual adapts to a new environment.
the change in the physical appearance of an individual over time.
a change in the genetic make - up of a population over time.

Explanation:

Question 4

In evolutionary biology, "fitness" is defined by an individual's ability to pass on its genes to the next generation. Having the most offspring means more genes are passed on. New mutations don't guarantee fitness, speed/strength alone don't ensure gene propagation.

Evolution is a population - level, long - term process. It's the change in the genetic composition of a population over generations. Adapting to aquatic environments is a specific adaptation, not evolution. Evolution isn't random/immediate at the individual level, and it's not about an individual's physical appearance change.

Answer:

C. the individuals that leave the most offspring.
