Till which year Nepal was a Monarchy?

The correct answer is Option 4: 2008

Pakistan and Bangladesh have experienced both civilian and military rulers, with Bangladesh remaining a democracy in the post-Cold War period. Pakistan began the postCold War period with successive democratic governments under Benazir Bhutto and Nawaz Sharif respectively. But it suffered a military coup in 1999. It has been run by a civilian government again since 2008. Till 2006, Nepal was a constitutional monarchy with the danger of the king taking over executive powers. In 2008, the monarchy was abolished and Nepal emerged as a democratic republic.
