Answer:

b The other fossils are about 300 million years old

Explanation:

From the description of the problem given, we can correctly conclude that the other fossils are about 300 million years old and even the rock layers formed around that period in time too.

  • Fossils are the preserved remains of organisms that has once lived.
  • Through the principle of relative dating we can determine the age of fossils and those of other related ones.
  • According to the principle of fossil and fauna succession, "fossils succeed one another in a predetermined form".
  • So, the fossils occurring together within the rock layers are of the same age.
