# Nuclear transmutation process

The above diagram shows the changes in the mass number and number of proton when an atomic nucleus $$\text{A}( _{ 92 }^{ 238 }{ U } )$$ becomes $$\text{E}( _{92 }^{ 235}{ U } )$$ by the nuclear transmutation process $\text{A } \rightarrow \text{B } \rightarrow \text{C } \rightarrow \text{D } \rightarrow \text{E.}$ Which of the following is true?
