Answer: option (2)
Explanation:
Relative dating is the efficient method that helps in determining events that has taken place in the past and also helps in identifying the older and the younger rocks. The events that are determined using this method, can clearly mark the boundary between the rocks of two distinct ages. It does not provide the exact age of an object or a fossil, thereby being its limitation but it gives the overall stratigraphy of the area.
Thus the correct answer is option (2)
