The correct option is D
The English Parliament is called the legislative power of the Kingdom of England. Its roots go back to the beginning of the medieval period. Throughout various developments, it gradually reduced the power of the monarch, and ended, after the Act of Union (1707), for being the main base of the Parliament of Great Britain, and in 1801, of the Parliament of the United Kingdom. This makes the modern Parliament of the United Kingdom one of the oldest legislative bodies in the world, probably the one that has more seniority, and for this reason is sometimes called the "Mother of all Parliaments."
It is the monarch who officially appoints the prime minister, but tradition requires him to elect the person with the majority support of the House of Commons, who is usually the leader of the party with a majority of seats in that chamber. If the prime minister loses that support (for the approval of a motion of censorship, for example), the convention forces him to resign, or to dissolve the parliament. However, if he has opted for dissolution and in the elections that follow does not achieve a parliamentary majority, he has no other option but to resign.
The King appoints the prime minister, and at the proposal of the latter, the monarch appoints the members of the Cabinet and the other ministers of the Government.
