A population of Daphnia in a crystal clear lake (Lake A) has genetic variation that increases melaninproduction and helps with the very high UV light exposure at this particular lake. But when members of this Daphnia population are transplanted to another lake (Lake B) with similar conditions except UV radiation is much reduced, the Lake A Daphnia are out competed by the Daphnia that are native to Lake B. Which of the following best explains this?a. The UV exposure in the Lake A Daphnia made them less fit.b. This isn't possible because the Lake A Daphnia will always be more fit.c. Evolutionary changes can be advantageous under some environmental conditions but disadvantageous under othersd. UV resistant phenotypes always out-compete non-resistant phenotypese. Evolution always maximizes the improvement or progress of a species
