The correct option is:
**d. the part of the skull surrounding the brain grew larger as hominins evolved.**
The fossil record indicates that as hominins evolved, there was a trend toward an increase in cranial capacity, suggesting that the brain size increased over time. This is accompanied by changes in other aspects of the skull, such as a reduction in the size of the brow ridges and changes in the shape of the face, but the increase in brain size is a significant trend observed in the fossil record.
