Option (D) presence of Hox is correct.

Animals ranging from corals to monkeys have the presence of Hox in common.

Hox genes, a subset of homeobox genes, are a collection of linked genes that define areas of an embryo's body plan along the animal head-to-tail axis.
Hox proteins determine and encode the qualities of "position," ensuring that the right structures form in the right locations throughout the body.

The genetic underpinning of embryonic patterning is shared by all metazoans due to the extraordinary interspecies conservation of these genes.
There are a total of 39 Hox genes in vertebrates, specifically in humans and mice, and they are divided into 4 different clusters.
The fast diversification of the body plans of all Bilaterians has been attributed in large part to the growth and evolution of the Hox genes.
