Correct answer: C. 235U
- A. 233U
- B. 238U
- C. 235U
- D. 239U
Explanation
C is the right option because: Enriched uranium is better as a fuel for a nuclear reactor because it has a greater proportion of uranium-235 (235U). Uranium-235 is the isotope primarily responsible for sustaining a chain reaction in nuclear reactors. By increasing the proportion of 235U in natural uranium, the efficiency of the reactor can be improved.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
