Details of two substances are provided. Substance P: conducts electricity well in both the solid state and the molten state; when placed in water, it reacts vigorously to form an alkaline solution; melting point $454\,\text{K}$. Substance Q: does not conduct electricity in any state; when placed in water, it reacts vigorously to form an acidic solution; melting point $317\,\text{K}$. Which row gives the structure and bonding for substances P and Q?
- AP: giant metallic, Q: simple molecular
- BP: simple molecular, Q: giant metallic
- CP: giant ionic, Q: simple molecular
- DP: giant metallic, Q: giant ionic
