A Correct answer
Explanation

Uranium-238 is the most abundant isotope of uranium but is NOT suitable for nuclear fission reactors because it is not fissile - it does not readily undergo fission when struck by thermal neutrons. Uranium-235 and Plutonium-239 are the preferred fissile materials used in nuclear reactors and weapons.
