Which statement about the giraffes explains their evolution based on Charles Darwin’s main points?
The closest fossil ancestor to these giraffes would have a very short neck.
All three of the giraffes have an equal chance of reproducing regardless of the environment.
As a giraffe reached for food, the giraffe could make its neck longer making it better adapted to the environment.
Long necks were a random genetic change and resulted in the gradual increase of organisms with long necks.

"Long necks were a random genetic change and resulted in the gradual increase of organisms with long necks."

This matches Darwinian natural selection: heritable variation arises (effectively random), individuals with beneficial traits (longer necks) have higher reproductive success in the given environment, and those traits become more common over generations. The other choices describe Lamarckian use-and-inheritance, equal fitness (which contradicts selection), or make an unwarranted fossil claim.
