d. Гідроген, Оксиген, Карбон

Три перші місця за поширенням у живій природі займають гідроген (H), оксиген (O) та карбон (C). Ці хімічні елементи є найпоширенішими в органічних сполуках та живих організмах, включаючи живі клітини. Гідроген і карбон складають основну структуру органічних сполук, таких як вуглеводи, жири, білки та нуклеїнові кислоти. Оксиген входить в склад багатьох сполук, забезпечуючи процеси дихання та окислення, що є важливими для забезпечення енергетичних потреб клітин.
