Answer

Brief Explanations:

The topic is about water being an important resource. The first option is about cost, the third introduces energy (off - topic), the fourth about water coverage (not about importance). The second option "With a little effort, people could easily protect this resource by conserving it" connects back to water as an important resource (by suggesting protection).

Answer:

With a little effort, people could easily protect this resource by conserving it.
