- B.
Plutonium - 239
- C.
Uranium - 237

Uranium - 238
Attempted by 3 students.
Show answer & explanation
Correct answer: B
The question asks which element is fissile. Plutonium-239 is the fissile material capable of sustaining a nuclear chain reaction. In contrast, thorium-232 and uranium-238 are catalytic isotopes that need to be converted into fissile material before they can be used in reactors. Therefore, plutonium-239 is the correct answer.
