Best answer
Correct answer is (d) U.V rays and lightening

The best I can explain: All the synthetic processes obtained energy from the Sun and lightening. Also, other alternate sources like volcanic eruptions and ionizing radiations like X-rays. These were the only available sources of energy during primitive time.
