Answer:
Option B. Some high islands in Melanesia and Polynesia are active volcanoes.
Step-by-step explanation:
Melanesia and Polynesia are both part of what is known as the Pacific Islands. The region of the Pacific North of Australia that borders Indonesia to the east is called Melanesia that contains islands such as Papua New Guinea, Fiji and the Solomon Islands. The largest region of the Pacific Islands is Polynesia, a land of many Islands groups with large distances between them. Both Polynesia and Melanesia have what is called "high islands" that were created as volcanic eruption build up. Over time this activity created land with a steep central peak, hence the name. These high islands are known to be areas in which there are several active volcanoes such as the Kavachi in Solomon Islands and Macdonald and Mehetia in the Polynesia.
