BMore primitive organisms evolved earlier so it is more likely that a primitive organism is older than a more complex one.

Answer;

B) probably the primitive organism on the left

Explanation;

The first living organisms we have proof of thanks to fossils, are three and a half billion years old.

Organisms which possess simple body organisation are called primitive organism. They differ from so called advanced organisms as all the activities of life are performed by a single cell.

Primitive organisms do not change their body design so easily as advanced organisms do. Prokaryotes are considered to be primitive forms and eukaryotes are the advanced organisms.

Advanced organisms are complex and have acquired new features morphologically and anatomically by evolution from simpler organisms to better adapt the changing environmental conditions.
