Correct Option:
Animal Kingdom of living things consists entirely of multi-celled, heterotrophic organisms.
Option: A
Step-by-step explanation:
The system of scientific classification in biological science is categorized into seven main groups: kingdom > phylum > class > order > family > genus > species. Here the kingdom is the largest group while smallest is the species. The term phylum is being used in the Kingdom of Animals, and is the second largest group.
The Kingdom of Animals is made up of multi-cellular, heterotrophic species which feed on other entities to survive. Some of the animal properties in this kingdom are able to establish, function independently, and reproduce during their existence.
