The correct answer is D. Puncak Jaya, Indonesia.
Puncak Jaya, also known as Carstensz Pyramid, is the highest mountain peak of Oceania, with a summit elevation of 4,884 metres (16,024 ft) above sea level. It is located in the Sudirman Range on the island of New Guinea, which is divided between Indonesia and Papua New Guinea. The mountain is part of the Maoke Mountains, which are the highest mountain range in Oceania.
Puncak Jaya is a dormant stratovolcano and is the highest point on the island of New Guinea. It is also the highest point in Indonesia and the Oceania region. The mountain is located in the province of Papua, Indonesia.
Puncak Jaya is a popular destination for mountaineers. The first ascent of the mountain was made in 1962 by a Dutch expedition led by Hendrikus van Heutsz. The mountain is also known for its glaciers, which are the only glaciers in the tropics.
The other options are incorrect because they are not the highest mountain peaks of Oceania. Mt. Victoria, Papua New Guinea is the highest mountain peak in Papua New Guinea, but it is not the highest mountain peak in Oceania. Mt. Kosciusko, Australia is the highest mountain peak in Australia, but it is not the highest mountain peak in Oceania. Mt. Cook, South Island (New Zealand) is the highest mountain peak in New Zealand, but it is not the highest mountain peak in Oceania.
