Answer:
C. Individuals with thicker fur had a survival advantage in the cold, allowing these individuals to reproduce moe often and create more offspring.

Natural selection means the process of changing the adapting the new environment. Based on the given data one can conclude that the individual with thicker fur had a survival advantage in the cold environment.
Why natural selection occurs?
Natural selection takes place due to 3 underlying reasons:
Reproduction
Heredity
Variation in fitness of organisms.
Due to these reasons, natural selection can leads to speciation.
As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.
Thus, option C is correct.
