Superficial nonelastic cleavage occurs in

Solution
The correct option is D Insects
Superficial cleavage is characterised by karyokinesis which leads to the formation of multiple nuclei but lacks cytokinesis. With the yolk positioned in the centre of the egg cell, the nuclei migrate to the periphery of the egg and the plasma membrane grows inward, partitioning the nuclei into individual cells. Superficial cleavage occurs in arthropods (including insects) that have centrolecithal egg cells.
Therefore, the correct answer is option D.
