The correct option is C Incomplete
Meroblastic cleavage takes place in those eggs where the amount of yolk is high, which leads to the partial or incomplete cleavage. It is basically of two types spherical and discoidal. The discoidal type of cleavage takes place in the reptiles and birds whose eggs are telolecithal in nature. The cleavage furrow does penetrate the yolk. In superficial cleavage, the cytokinesis does not take place and it leads to a polynuclear egg. Superficial cleavage takes place in the arthropods. So, the correct option is 'Incomplete'
