The correct option is C Towards vegetal pole
Many vertebrate eggs are telolecithal, meaning they have large amounts of yolk concentrated at one end of the cell, known as the vegetal pole. The opposite, more metabolically active pole is the animal pole. The eggs of amphibians are moderately telolecithal (mesolecithal). The telolecithal eggs of reptiles and birds have very large amounts of yolk at the vegetal pole and only a small amount of cytoplasm concentrated at the animal pole.
