• A. Tritium
• B. Protium
• C. Deuterium
• D. All Of These

Answer 1

The correct option is D

All Of These

Explanation for correct option

(D)All of these

Isotopes

• Atoms with identical atomic numbers but different mass numbers are known as Isotopes.
• The isotopes of hydrogen are protium$\left({}_1{}^1\mathrm{H}\right)$, deuterium$\left({}_1{}^2\mathrm{H}\right)$, and tritium $\left({}_1{}^3\mathrm{H}\right)$.

Explanation for incorrect option

Protium, deuterium, and tritium are isotopes of hydrogen. Hence, all the options are correct.

Hence, option (D) is the correct option. The isotopes of hydrogen are protium$\left({}_1{}^1\mathrm{H}\right)$, deuterium$\left({}_1{}^2\mathrm{H}\right)$, and tritium $\left({}_1{}^3\mathrm{H}\right)$.
