Answer:

D. The proportion of mottled fish will increase over time.

Explanation:

In a lake with mottled appearance mottled fish will have advantage over the light brown fishes because light fishes would be easy to be seen by predators.

The proportion of mottled fish will increase over time because of the natural selection. Natural selection is evolutionary mechanism which changes the frequency of a certain allele (consequently, gene and phenotype) by favouring traits (structures, behavior) of an organism that help him survive and reproduce. In the example, above, mottled fish have mottled phenotype that help them survive and reproduce so it will be favorable trait by natural selection.
