WILL REWARD BRAINLIEST A thermonuclear fusion reaction cannot be maintained in the oceans of Earth because

A)the deuterium in the ocean is not radioactive.

B)the density is not high enough.

C) there is insufficient deuterium in the ocean.

D)the temperature is not high enough.

D) the temperature is not high enough.

Explanation:

The nuclear fusion reactions involve the fusion of the nucleus of the heavy metals. This is done in a nuclear reactor and energy is produced in the heat energy along with radiations. This system requires heat energy for the accomplishment of the nuclear reactions. The temperature of the system cannot be maintained inside the ocean so nuclear fusion will not occur in the ocean.
