Question

which of these is a concern with respect to using fuel cell cars?
○ use of non - renewable resources
○ cost of the distribution network
○ battery recharge or replacement
○ reliance on petroleum products

Explanation:

• Fuel cell cars use hydrogen (often produced from various sources, not just non - renewable or petroleum - based), so "use of non - renewable resources" and "reliance on petroleum products" are incorrect.
• Fuel cell cars don't rely on batteries (they use fuel cells to generate electricity), so "battery recharge or replacement" is incorrect.
• Building a distribution network for hydrogen (fuel for fuel cell cars) is costly, making this a concern.

Answer:

B. cost of the distribution network
