The correct option is A Pervez Musharraf
In 1999, General Pervez Musharraf led a military coup, which overthrew the democratically elected government. A military coup is when armed forces are used to overthrow an existing government. He later declared himself the President of Pakistan. In 2000, he held a referendum to extend his presidency by five years. The vote came through, and his presidency was extended. However, he has been accused by the media and many democracy activists of electoral fraud on the referendum.
