Vedclass · Answer

(A) Megalecithal or macrolecithal eggs are those that contain a very large amount of yolk. This type of egg is characteristic of organisms that require significant energy reserves for embryonic development before hatching. Reptiles and birds (Aves) produce megalecithal eggs to support the development of the embryo outside the mother's body. Monotremes (egg-laying mammals) also produce megalecithal eggs. Therefore,the correct group containing megalecithal eggs is reptiles,birds,and monotremes.
