Which of the following statements is true?
nuclear power plants can decrease fish populations.
solar power is expensive and not widely used.
coal and oil are considered nonrenewable resources.
all of the above.

The correct answer is the third option: Coal and oil are considered nonrenewable resources.

Explanation:

A nonrenewable resource is a substance that is being used up more quickly than it can replenish itself.

Coal and oil are fossil fuels, and are examples of nonrenewable resources that humans constantly use.

Nuclear power plants can decrease fish population: this statement is not true because nuclear power plants produce renewable, clean energy. They do not pollute the air or release greenhouse gases, can be built anywhere and do not alter the environment around them by much.

Solar power is expensive and not widely used: this statement is also not correct because solar power is now relatively affordable and is actually widely, if not commonly, used both in urban and rural areas.
