The correct answers are:

3. Great Barrier Reef - Australia's natural wonder that can be seen from space;

This is the biggest coral reef in the whole world, and it stretches along the eastern and northeastern coast of Australia;

4. Ring of Fire - D. 75 percent of the world's active volcanoes are located here;

The Ring of Fire is located alongside the boundary of the Pacific plate with the other plates, and since there's subduction zones all over its boundary, there's lots of active volcanoes.
