Question Analysis
This question involves the relationship between ionic compound structure, interionic forces, and physical properties (melting and boiling points). The main focus is on identifying the root cause of the high melting and boiling points of ionic compounds.

Key Concept Explanation
Ionic compounds have high melting and boiling points due to the strong electrostatic attractions between the oppositely charged ions. These attractions require a significant amount of energy to overcome, leading to high melting and boiling points.

Step-by-step Solution
1. Recall the structural basis of ionic compounds: Ionic compounds consist of a lattice of cations and anions held by electrostatic attractions.
2. Link structure to melting/boiling requirement: To melt or boil an ionic compound, the strong electrostatic forces between ions must be overcome.
3. Evaluate each option:
Option A: Incorrect. Ionic compounds ...
