The correct option is A Telolecithal
Telolecithal eggs are those eggs in which the yolk is concentrated at one pole of the egg separate from the developing embryo which refers to the uneven distribution of yolk in the cytoplasm of ovums. This type of egg undergoes discodial meroblastic cleavage, where yolk does not include in the cells during cell division. For example in birds, reptiles and fishes. Therefore, frog being an amphibian, its egg is telolecithal. Hence, Option A is correct.
