The correct answer is - A. larger and more rounded.
The modern humans have brain that significantly differs in size, but also in shape, compared to the brains of the hominid ancestors. The brain of the modern humans is larger, by far, and also it is more rounded and better developed, which has also led to the bone structure of the head to be more rounded. The brains of the hominid ancestors were smaller, but also more flattened, which can also be easily seen by the structure of the skull, more elongated and flattened.
It has differences between one ancestor and another, because as the evolution was going, every next ancestor in the line had slightly larger and slightly more rounded brain, so the difference is bigger with the older ancestors, and smaller with the more recent ones.
Fossils, they show us many different things, for example dinosaur bones show us how they acted in the past, and links to what animals that are still alive today. Second, is that fossils, human fossils turn into Carbon to which makes diamonds and coal to help us in everyday life. And finally, Fossils show us how living things have changed over the years.
I hope that helps, to be honest I'm not good at science either but I hope you get better soon..
