A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season

The observation that best supports the idea that increased competition causes changes in a species is:
A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season.
This observation illustrates how a trait (larger antlers) can provide a competitive advantage during mating, leading to greater reproductive success (a key aspect of natural selection) and resulting in changes in the population over generations.
