Solution

The correct option is A Atomic oxygen
In cellular respiration: NADH and FADH2 are converted to ATP through an electron transport chain with oxygen as the 'terminal electron acceptor'. Oxygen is the final electron acceptor. This is the only reason oxygen is required for living systems.
So, the correct option is 'Atomic oxygen'.
