Answer: most specimen that have lived on earth is still living here on earth

Explanation:

The statement correct about fossil record is option b. Extinction is rare a rare event and rarely seen in the fossil records.

Fossils are the preserved remains of decomposed plants and animals. There are mainly two types of fossils namely , body fossils and trace fossils. Body fossils include bones, skull, and other body parts.

Trace fossils are traces of some actions of organisms that lived in earth. For example foot prints, caves, shells etc. The entire  fossils—both known and unknown—along with their placement in strata and fossiliferous  rock formations are collectively referred to as the fossil record.

The fossil record was one of the earliest data sources used to support the study of evolution and is still important for understanding the evolution of life on Earth. Geologists can now calculate the numerical or absolute age of different strata.  It records extinction of some animals and plants as rare event.
