Explanation:

Indonesia’s Mount Sinabung volcano erupted, sending a column of ash and smoke more than 16,000 feet into the air. The volcano, which is situated in North Sumatra, has been active since 2010. Indonesia is home to many active volcanoes, due to its position on the “Ring of Fire”, or the Circum-Pacific Belt, which is an area along the Pacific Ocean characterised by active volcanoes and frequent earthquakes. The Ring of Fire is home to about 75 per cent of the world’s volcanoes and about 90 per cent of its earthquakes. Hence option 3rd is correct.
