I believe the answer is: B. It became a democracy in the 1980s.
Prior to the adoption of Democratic system, Nepal was referred to as The kingdom of Nepal, which adopted a monarchy system of Government.
But many of leaders rule with dictatorships and resentment started to build up among Citizens. This lead to people's movement that demanded the change of government system into a democracy.
