Which of the following statements is true?

The statement about rodents having a good sense of smell is true. Rodents, such as rats and mice, are known for their keen sensory perceptions, particularly their olfactory capabilities. This strong sense of smell helps them locate food, identify predators, and communicate with other rodents through pheromones.

While the other options may seem plausible, they are not accurate in the context of typical rodent behavior. Rodents generally do not live in isolation; they are social creatures and often live in groups, which provides safety and improves their chances of finding food. Additionally, rodents do require water for survival, typically obtaining it from food sources and drinking it directly when necessary. Thus, the combination of these facts leads to the understanding that rodents are indeed adapted to their environments with specific needs, and acknowledging their sensory abilities is particularly essential in managing and controlling rodent populations.
