Alexis Morgan · Answer 1

The correct option is C) An allele frequency changes in a population.

Explanation:

Natural selection tends to favour those organisms which can adapt to changes in the environment and pass on their characteristics to their offsprings. A change in the allele frequency of a population will arise when certain organisms of the species become more adapted to live in a particular environment. The other organisms with not so favourable might get completely eradicated from the environment and hence evolution will occur.
