In the nuclear reaction
${ }_{11}^{23} \mathrm{Na}+\mathrm{X} \rightarrow \mathrm{Y}+{ }_0^1 \mathrm{n}$
X and Y are

• Correct answer
  A

  ${ }_1^1 \mathrm{H}$ and ${ }_{12}^{23} \mathrm{Mg}$
• B

  ${ }_2^4 \mathrm{He}$ and ${ }_{13}^{27} \mathrm{Al}$
• C

  ${ }_1^1 \mathrm{H}$ and ${ }_{12}^{24} \mathrm{Mg}$
• D

  ${ }_1^2 \mathrm{H}$ and ${ }_{12}^{23} \mathrm{Mg}$

Hence, the correct answer is option: 'A'.
