Answer 1

The correct answer will be option-D

Step-by-step explanation:

Indonesia country is located at the point where two tectonic plates meet that is between the Eurasian Plate and the Australian Plate.

The western part of Indonesia was formed by the volcanic eruptions like Sumatra, Bali and Java whereas the eastern part of Indonesia was formed by the movement of the Australian and Pacific tectonic plates.

The species living in western Indonesia has Rhinos and Tigers whereas Eastern islands have kangaroos and cockatoos. The difference lies in the fact that the western animals could have migrated before tectonic plate separation from Asia while the Eastern animals from Australia.

Thus, Option-D is the correct answer.
