The evolution of long necks in giraffes is best explained by option C: Giraffes with longer necks survived because they were better suited to the environment. This explanation is rooted in the concept of natural selection, where individuals with traits that provide advantages in their environment are more likely to survive and reproduce. In the case of giraffes, longer necks may have provided advantages in reaching food in taller trees or in competing for mates, which would lead to the prevalence of this trait over generations.
