(B) The eggshell of a bird is porous, which allows for the exchange of gases ($O_2$ and $CO_2$) between the developing embryo and the external environment.Plaster of Paris $(CaSO_4 \cdot 1/2 H_2O)$ forms a hard, non-porous layer when it sets.If the egg is covered with this material, the pores in the shell are blocked.This prevents the diffusion of gases, thereby hindering the respiration of the developing chick embryo, which eventually leads to its death.
