An isotope of polonium is represented by the nuclide notation $^{218}_{84}\text{Po}$. The nucleus of this isotope undergoes decay by releasing an $\alpha$-particle. After that, a $\beta$-particle is emitted and nuclide X is formed. What notation represents nuclide X?
- A$^{214}_{81}\text{X}$
- B$^{213}_{82}\text{X}$
- C$^{213}_{83}\text{X}$
- D$^{214}_{83}\text{X}$
