It began no more than 23,000 years ago. 

Answer:

Option (4)

Explanation:

The hotspots are the region where the magma from the greater depth rises upward in large columns, as the convection currents exert a large amount of force. There are numerous hotspots on earth and are located away from the tectonic plates. These are generally formed when tectonic plates move over the region of hotspots.

As the oldest rocks of Mount Kilauea are found to be 23000 years old, so it can be concluded that the hotspot that is located below Hawaii began more than 23,000 years back.

Thus, the correct answer is option (4).
