D volcanic eruption

Answer 1

The change from a large island to many smaller islands could most likely be caused by D. volcanic eruption.

Volcanic eruptions can create new landforms and can fragment existing land, potentially leading to the creation of multiple smaller islands as lava flows or explosive eruptions alter the landscape. Tsunamis can erode land, but they are more likely to reshape rather than create smaller islands. Mudslides and wind erosion are less likely to cause the emergence of new islands in that manner.
