Solution
The correct option is B by spitting or sneezing By spitting or sneezing we can get off.
Since there is no friction present we need to spit or sneeze which will produce a suitable friction to get off. Also this will produce a momentum in opposite direction which will help us to move in opposite direcdtion.
