B Correct answer
Explanation

Mesolecithal eggs have moderate yolk quantity (between oligolecithal and macrolecithal). They undergo holoblastic cleavage (complete division) but it is unequal - the vegetal pole (yolk-rich) divides slower than the animal pole. This is characteristic of amphibians like frogs. Meroblastic (incomplete) cleavage occurs in macrolecithal eggs.
