The correct option is : "Indonesia"
The geography of Indonesia is dominated by volcanoes that were formed by subduction zones between the Eurasian plate and the Indo-Australian plate. Some of the volcanoes stand out for their eruptions, such as Krakatoa for its global effects in 1883, Toba for its supervolcanic eruption that occurred approximately 74,000 years ago and which was responsible for six years of volcanic winter, and Tambora for the eruption of 1815, the most violent in recorded history.
The volcanoes in Indonesia are part of the Pacific Ring of Fire. The 150 volcanoes included in the following list are grouped into six geographic regions, four of which belong to the volcanoes of the fossa system of the Arco de Sonda. The other two groups are Halmahera volcanoes, including the surrounding volcanic islands and the Sulawesi volcanoes and the Sangihe islands. This last group is part of the same volcanic arc as the volcanoes of the Philippines.
