• B. They take millions of years to renew.
• C. They are renewable sources of energy.
• D. They are non-conventional sources of energy.

The correct option is B

They take millions of years to renew.

Fossil fuels take millions of years to form. They cannot be replenished if we keep using them at our present consumption rate. Therefore, it is important to conserve them by using alternative sources of energy.
