b. can no longer undergo cell division.
Explanation:
Terminally differentiated cells are those cells completely specialized in their functions that have lost their ability to proliferate. They are cells that have a unique, very specific, function, whereas undifferentiated cells do not have specialized functions that serve to replace old and dead cells. Examples of terminally differentiated cells include skin cells derived from epithelial stem cells, red blood cells and white blood cells generated from hematopoietic stem cells, etc.
Clues such as fossils such as bones, footprints, tar, etc, preserved underground helped inform scientists. You can also count how old a tree is when you cut it open and there are some alive for thousands of years so that is a possible way.
