Question

deuterium is an isotope of hydrogen. from where could deuterium be obtained for use in the process of nuclear fusion? a. deuterium is a waste product of nuclear fission. b. deuterium is common in seawater. c. deuterium can be harnessed from the sun. d. deuterium is produced in a laboratory.

Explanation:

Seawater contains a small but abundant concentration of deuterium (in the form of heavy water, $\text{D}_2\text{O}$), making it the primary practical source for deuterium used in nuclear fusion research. Nuclear fission does not produce deuterium as waste, deuterium cannot be harnessed directly from the sun, and while it can be synthesized in a lab, this is not a practical source for large-scale fusion use.

Answer:

B. Deuterium is common in seawater.
