Solution

The correct options are
A The diagram represents radioactive decay of Uranium-238
B Radon gas is released during radioactive decay of Uranium-238
C Parent of Radon-222 is Radium-226
D Thorium formed in this process is also a radioactive element
Uranium-238 is the most common isotope of uranium found in nature. Uranium undergoes radioactive decay in a chain reaction, forming other unstable nuclei. During the decay of uranium, radon gas is formed.The parent of radon-222 is radium-226. All these elements are sources of radioactivity.
