Detailed Explanation

The correct option is A. Chain and Dimeric.

In solid-state beryllium chloride (BeCl ) exist as (BeCl ) polymeric chain.

In the vapour phase, above 900 C beryllium chloride (BeCl ) is monomeric having a linear structure Cl - Be - Cl.

The bonding in (BeCl ) is covalent and Be atoms accommodate the two sp-hybrid orbitals.

Below 900 C, beryllium chloride exists as a mixture of monomer (BeCl ) and dimer (BeCl ) .
