Answer:
A. ability to make food and ability to swim
Step-by-step explanation:
Living organisms have been grouped into an hierarchical system of classification that begins with the kingdom, which is the most inclusive taxon. Organisms were placed into kingdoms based on two major criteria namely; their nutrition and mobility.
Their nutrition depends on their ability to make food by themselves (autotrophic) or not (heterotrophic) while their mobility depends on their possession of structures for locomotion.
