The correct answer is:
**C. The grass will shrivel and die, which will cause a decrease in the impala population.**
In a drought, the lack of water leads to the grass becoming dry and potentially dying off. Since impalas depend on grass as a primary food source, a decline in grass will result in a decrease in the impala population. This, in turn, would likely affect any predators that rely on impalas for food, such as cheetahs, but the immediate effect in this scenario pertains to the relationship between the grass and the impala population.
