The correct Answer is:
To determine which of the following is an artificial fuel for nuclear reactors, we need to analyze each option provided: 1. **Understanding the Options**: - **Uranium-238 (U-238)**: This is a naturally occurring isotope of uranium. It is the most abundant isotope of uranium found in nature. - **Plutonium-239 (Pu-239)**: This isotope is not found in significant amounts in nature and is produced artificially in nuclear reactors from U-238 through neutron capture and beta decay. - **Uranium-235 (U-235)**: This is another naturally occurring isotope of uranium, though it is much less abundant than U-238. - **Thorium-232 (Th-232)**: This is a naturally occurring isotope of thorium. 2. **Identifying Artificial Fuels**: - Artificial fuels are those that are not found in nature in significant quantities and are produced through human processes. - Among the options, U-238, U-235, and Th-232 are naturally occurring isotopes. In contrast, Pu-239 is produced artificially. 3. **Conclusion**: - Since the question specifically asks for an artificial fuel for nuclear reactors, the correct answer is **Plutonium-239 (Pu-239)**. Thus, the answer is **b. Pu-239**.
