B) all organisms are composed of exactly the same proteins.
C) the same homeotic mutations are likely to appear in all organisms.
D) essentially we can complete the genome mapping of all animals in a short time.
E) structures remain fairly constant, but regulation of animal development varies widely across the kingdom.
Homeotic Genes
Genes that control the overall body plan by controlling the fate of groups of cells during development.
Organisms
Any individual living entity, ranging from microorganisms like bacteria to multicellular forms such as plants, animals, and humans.

Final Answer :
A
Explanation :
The presence of the same homeotic genes in a wide range of organisms indicates that these genes evolved early in the history of life, and have been conserved throughout evolution. This conservation suggests that these genes are important for the proper development of the body plan in many different organisms.
