Which statement is a pro of solar energy?

• A. High efficiency (95%), non polluting, low environmental impact, solar systems last 20-40 years
• B. Solar energy is always available regardless of weather.
• C. Solar panels produce significant air pollution during operation.
• D. Solar energy requires constant fuel supply.

Answer: (A)

The main idea being tested is the advantages of solar energy. The best statement highlights real benefits: solar energy operates without emitting pollutants during use and solar systems have a long lifespan (roughly 20–40 years), which means clean energy with low ongoing maintenance over a long period. While the claim about very high efficiency isn’t typical for solar panels, the emphasis on being non-polluting and durable reflects true pros of solar energy. The other statements aren’t correct because solar isn’t available all the time (it depends on sunlight and weather), it doesn’t produce significant air pollution during operation, and it doesn’t require a constant fuel supply.
