The correct option is D A and C only
Endothecium is the lining of the cavity of an anther which lies behind epidermis. Synergids are haploid in nature, which are present in the embryo sac, safeguarding the egg cells. It is vestigial in nature. Fusion of egg with male gamete is called as syngamy. Raphe is a ridge connecting the hilum with the chalaza.
