The correct option is D If the government loses the majority in ‘no-confidence motion’, then it has to resign.
A no-confidence motion can be moved by a Lok Sabha MP, if he or she feels that the govt in power is not functioning properly. If more than 50 MPs support the motion, a debate is initiated. It can be brought up against the incumbent government. If the government loses the majority in ‘no-confidence motion’, then it has to resign.
