The key point is the mutation (variation) exists in the population before the environment changing. For C, if the environment does not change, though the adaptation is useful to environment, it will not be selected. Because the organisms without the adaptation will not die.

Glomar Challenger missions started in 1968. The drilling ship collected cores, or long cylinders of sediment and rock beneath the seabed. The cores confirmed the theory of seafloor spreading and tectonic plates. Collected data also showed evidence of change in the earth's climate throughout history, as well as evolutionary clues.
