Question: what type of mountain is cho oyu?
Answer: Cho Oyu is considered the easiest eight-thousander, with the lowest death-summit ratio (​1⁄25th of Annapurna's). It is the second most climbed eight-thousander after Everest (whose height makes it the most popular), and has over four times the ascents of the third most popular eight-thousander, Gasherbrum II.
