detailed solution

Correct option is A

(1) BeCO3 is unstable to the extent that it is stable only in an atmosphere of CO2. BeCO3 shows a reversible reaction because the stability of oxide formed is more than carbonates.BeCO3⇌BeO+CO2BeCO3 is unstable due to the strong polarising effect of small Be2+ ions on the large polarisable carbonation. Moreover, extra stability of the oxide achieved through lattice energy by packing small cation with a small oxide ion.
