Suppose a species of snake is living in a certain area. Some of the snakes in the population are black and some are orange. Over time, the area changes and the orange snakes have a harder time blending in with the environment. This makes it difficult for the orange snakes to catch food.According to Darwin’s theory of evolution, what will most likely happen to this snake population over time?

A
Most orange snakes will survive and reproduce, passing on their traits to their offspring. Few black snakes will remain in the population.
B
Most black snakes will survive and reproduce, passing on their traits to their offspring. The number of orange snakes in the population will not change.
C
The black snakes will survive and reproduce, passing on their traits to their offspring. Few orange snakes will remain in the population.
D
Most orange snakes will survive and reproduce, passing on their traits to their offspring. The number of black snakes in the population will not change.
