Mount Fuji Volcano erupted few years back. It threw out fine, glass-rich ash into the atmosphere. It thereby disrupted air traffic and caused inconvenience to air travel. It might also erupt again in future. Mount Fuji is an example of Active Volcanoes. Active Volcanoes are those that have erupted in the past 10,000 years. Dormant Volcanoes are those volcanoes that haven't erupted in the past 10,000 years, but are expected to erupt again. Mount Kilimanjaro in Tanzania is a dormant volcano. Extinct Volcanoes are those that have not had an eruption for at least 10,000 years and are not expected to erupt again in any near future. Mount Kulal in Kenya is an extinct volcano. There is no such thing as Vulnerable Volcanoes. Hence, the right answer is Option D.
