Which among the following elements is abundant on the lunar surface and holds the potential to put an end to the energy crisis of the earth ?

Helium-3 (3He) is a light, stable isotope of helium that is extremely rare on Earth but abundant on the lunar surface [t3][t6]. It is deposited in the lunar regolith by solar winds over billions of years [t4]. Helium-3 is considered a revolutionary fuel for nuclear fusion because it enables aneutronic fusion reactions, such as the deuterium–helium-3 (D-3He) reaction, which produces minimal to no radioactive waste and allows for the direct conversion of energy into electricity [t5][t7]. While terrestrial reserves are insufficient for large-scale power, the Moon's supply could potentially meet global energy demands for centuries, offering a solution to the Earth's energy crisis [t1][t5]. The nomenclature 'Helium-III' in the options refers to this specific isotope (3He), distinguishing it from the common Helium-4 (4He) [t6].
