Solution
The correct option is D Santalaceae
Embryo sac in Santalaceae develops a micropylar tube that passes through the micropyle and enters the cavity of ovary and in some of them there is an antipodal tube. The young sac is broad above and narrowed toward the antipodal end. After fertilization the antipodal region develop rapidly, penetrates the chalaza, enters the placental axis and curving passes down to the base of the flower, where its tip dilates and becomes embedded in the vascular cup formed by three diverging carpellary bundles. Pseudo embryo sac - It contains several free nuclei and dense cytoplasm which are generally consumed by the developing embryo.
