Options
A Holoblastic cleavage divides the entire egg, meroblastic only part of it
Correct Answer
B Holoblastic occurs in birds, meroblastic in mammals
C Holoblastic produces more cells
D Meroblastic results in larval forms
Correct Answer

Option A is the correct answer.

Detailed Explanation

Holoblastic cleavage (complete) divides the entire egg cytoplasm, typical of isolecithal eggs. Meroblastic cleavage (incomplete) is restricted to a small disc of cytoplasm due to large amounts of yolk.

The prefix 'holo-' means whole, 'mero-' means part.
