The correct answer is C. The man who lived from 460 BC to 370 BC and was among the first to suggest the idea of atoms was Democritus.
Explanation:
Democritus was a Greek philosopher, astronomer, mathematician and traveler. He is counted among the presocrats and was known as "the laughing philosopher". Together with his teacher Leucippus, he was the founder of atomism. According to it, the cosmos consisted of emptiness (the non-existent) and bodies (atoms, the existence) in an infinite space. Those bodies are eternal and can move. Democritus wrote a lot: sixty titles are known. They were about ethics, philosophy of nature, mathematics, music, poetry and technical themes.
