The polynesian islands vary widely and can be divided into: a. sea islands and land islands.
b. wet islands and dry islands.
d. islands with high elevations and islands with low elevations

The correct answer is D. The Polynesian Islands vary widely and can be divided into islands with high elevations and islands with low elevations.

Explanation:

Polynesia is the name given to a set of islands in the South Pacific Ocean.  Extended over a huge ocean surface, it has a combined area of 298,000 km² and 4.5 million inhabitants. Its larger islands have volcanic origin and high elevations, and the smaller ones have coralline origin with low elevations. Given that the entire territory of Polynesia lies between the tropics, it has a very hot and humid equatorial or tropical climate.
