The Family Tree That Includes Humans and Chimpanzees Is BEST

The family tree that includes humans and chimpanzees is BEST described how?

A) As a simple tree with two branches-one leading to chimps and one leading from early to modern humans.Only one species of early human was present on Earth at a time.
B) As a complex tree with two major branches-one leading to chimps and one leading to modern humans.The "human" tree itself has many branches,and multiple early human species were present at various times during human evolution.
C) As a complex tree with three major branches-one leading to chimps,one leading to Neanderthal Man,and one leading to modern humans.Only one species of early human was present on Earth at a time.
D) As a complex tree with two major braches-one leading to chimps and one leading to modern humans.The "human" tree has many branches,but only one species of early human was present on Earth at a time.
E) As a complex tree with many major branches-one to chimps and one to each of many early human species.A dozen or more early human species were present on Earth before anatomically modern humans arose.
