Question

which of these is a benefit of fuel cell cars?
○ fuel cell cars are inexpensive.
○ hydrogen fuel can be stored safely.
○ fuel cell cars do not release greenhouse gases.
○ hydrogen fuel can be distributed easily

Explanation:

• Option A: Fuel cell cars are generally expensive due to technology and production costs, so this is incorrect.
• Option B: Storing hydrogen fuel safely is challenging (requires special conditions), so this is not a benefit.
• Option C: Fuel cell cars produce electricity through a reaction that emits only water vapor, no greenhouse gases, making this a key benefit.
• Option D: Distributing hydrogen fuel is difficult (needs specialized infrastructure), so this is incorrect.

Answer:

C. Fuel cell cars do not release greenhouse gases.
