The correct option is C partial/parietal
Meroblastic cleavage
Meroblastic cleavage occurs in mesolecithal eggs. It is an incomplete, parietal or partial cleavage. Due to the abundant yolk present in the egg, the lines of segmentation do not completely pass through the egg and remain confined to the animal pole or peripheral region of the egg. Thus the yolk remains undivided. Examples include birds and reptiles.
Final answer:
(b) partial/parietal
