Bring out the only correct statement in context with Uranium?
Options:
A . Both U-235 and U-238 are fissile but only U-235 can sustain chain reactions
B . Only U-235 is fissile and can sustain chain reaction but U-238 is fertile
C . U-238 can be used in chain reactions only after extracting U-235 from it
D . Uranium enrichment is a process where concentration of U-238 is increased using some chemical processes
Answer: Option B
C is not correct because U-238 will support chain reactions after it is converted to plutonium-239. D is also incorrect because of its concentration of U-235 that matters.
