In natural uranium, the constituents of three naturally occurring isotopes are

A U<sub>234</sub> = 0.006%, U<sub>235</sub> = 0.712% and U<sub>238</sub> = 99.282%
B U<sub>234</sub> = 0.712%, U<sub>235</sub> = 0.006% and U<sub>238</sub> = 99.282%
C U<sub>234</sub> = 99.282%, U<sub>235</sub> = 0.006% and U<sub>238</sub> = 0.712%
D U<sub>234</sub> = 0.006%, U<sub>235</sub> = 99.282% and U<sub>238</sub> = 0.712%

Correct Answer: U<sub>234</sub> = 0.006%, U<sub>235</sub> = 0.712% and U<sub>238</sub> = 99.282%
