It's either B or C.

According to Cambridge:

"date back" phrasal verb

to have existed a particular length of time or since a particular time:

This tradition dates back to medieval times.

A using fire to cook food could be dated back to almost two million years and that it could explain hominid features like having
B the use of fire to cook food could date back almost two million years and could explain such hominid features as
C cooking food with fire could date back to almost two million Years, explaining hominid features like
D fire used to cook food could date back almost two million years ,explaining hominid features such as having.
E fire used for cooking food could be dated back to almost two million years and explain hominid features like.


Well I pick B for several reasons!
the use of fire is better as it is the use of fire that could explain the homnid features. Also B is parallel. The last reason is, the usage of such as. Like does not go well here.
