Answer:
A. Which do you think will run out first? Coal and oil or wind and
sunlight?
Step-by-step explanation:
Option A is rhetorical because wind and sunlight are infinitely available resources that have been available for an eternity, and they will always continue to exist. Therefore, there is only one possible answer to this question: coal and oil.
When making a comparison, if one answer is obviously wrong or illogical, it's likely the comparison is rhetorical.
