According to the research, the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.
<h3>What is Relative dating?</h3>
It consists of ordering fossils or events in a proper formation sequence from the oldest to the most modern, it tends to be used as a method for making chronologies, the ordering of events, fossils or rocks.
Since it does not give an exact or approximate date, they can only give us a fairly long period of time, or in their case a temporal ordering of the fossils.
Therefore, we can conclude that according to the research, the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.
