• A. The isotope of parent nucleus
• B. The isobar of parent nucleus
• C. The nuclide $\begin{array}{c}23\\ 11\end{array}Na$
• D. The isobar of $\begin{array}{c}23\\ 11\end{array}Na$

Answer 1

The correct option is C The nuclide $\begin{array}{c}23\\ 11\end{array}Na$

$\begin{array}{c}24\\ 12\end{array}Mg+\gamma \to \begin{array}{c}23\\ 11\end{array}Na+\begin{array}{c}1\\ 1\end{array}H$.
