Answer:
The correct answer is option (d)-"All of these are found in the fossil record and have been used by scientists to understand human evolution".
Explanation:

The fossil records that scientists has used understand human evolutionary patterns include the following. Ardipithecus ramidus bones that revealed advances in upright walking, even tough they had a small brain that measured between 300 and 350 cm3.
