Statement (B) is incorrect because interstitial compounds are extremely hard, rather than soft.

Formation: They form when small atoms like hydrogen, carbon, or nitrogen get trapped inside the metal lattice vacancies.

Conductivity: They retain their metallic conductivity because the electronic structure and metal-metal bonding remain largely intact.

Physical Properties: They exhibit high melting points (higher than pure metals) and become remarkably hard and chemically inert.
