Observe the following data.

Ion	\(\mathrm{Q}^{\mathrm{a}+}\)	\(\mathrm{X}^{\mathrm{b}+}\)	\(\mathrm{Y}^{\mathrm{c}+}\)	\(\mathrm{Z}^{\mathrm{d}+}\)
Radius (pm)	\(53\)	\(66\)	\(40\)	\(100\)

\(\mathrm{Q}^{\mathrm{a}+}, \mathrm{X}^{\mathrm{b}+}, \mathrm{Y}^{\mathrm{c}+}, \mathrm{Z}^{\mathrm{d}+}\) are respectively

1. A \(\mathrm{Mg}^{2+}, \mathrm{Al}^{3+}, \mathrm{Na}^{+}, \mathrm{Si}^{4+}\)
2. B \(\mathrm{A} l^{3+}, \mathrm{Si}^{4+}, \mathrm{Mg}^{2+}, \mathrm{Na}^{+}\)
3. C \(\mathrm{Mg}^{2+}, \mathrm{Si}^{4+}, \mathrm{Al}^{3+}, \mathrm{Na}^{+}\)
4. D \(\mathrm{A} l^{3+}, \mathrm{Mg}^{2+}, \mathrm{Si}^{4+}, \mathrm{Na}^{+}\)
