The Royal Anthem of Canada is:

Discover Canada records this in one direct sentence about the Royal Anthem. The guide writes: The Royal Anthem of Canada, "God Save the Queen (or King)," can be played or sung on any occasion when Canadians wish to honour the Sovereign. The anthem the test wants is therefore God Save the King (or Queen, depending on the reigning Sovereign).

Two precise commitments. Discover Canada commits the Royal Anthem to TWO specific facts: (1) the anthem is named "God Save the Queen (or King)"; (2) it is for occasions when Canadians wish to honour the Sovereign. So the source pinpoints both the name and the precise purpose: this anthem is sung specifically for the monarch.

Canada has TWO anthems with different roles. Discover Canada commits Canadian musical recognition to a clear distinction. The national anthem is O Canada — proclaimed in 1980. The Royal Anthem is God Save the Queen (or King) — sung when honouring the Sovereign. So the two anthems serve different occasions: one for national identity and one for the Crown. Both are part of Canadian official identity.

The Royal Anthem reflects Canada's constitutional monarchy. Discover Canada commits Canada's monarchical character to specific named principles: Canada is "a constitutional monarchy, a parliamentary democracy and a federal state." The Sovereign is the Head of State, while the Prime Minister is the Head of Government. The Crown has been "a symbol of the state in Canada for 400 years." So singing God Save the Queen (or King) at official occasions is part of Canada's continuing recognition of its constitutional monarchy. The anthem is included in the source's reproduced text — "God save our gracious Queen! Long live our noble Queen! God save the Queen! Send her victorious, Happy and glorious, Long to reign over us, God save the Queen!" — making clear the anthem's reverent role at any occasion when Canadians wish to honour the Sovereign. So when the test asks the Royal Anthem of Canada, the source-precise answer is God Save the King (or Queen).

The question is testing whether new citizens know the Royal Anthem of Canada. Discover Canada commits to one anthem: God Save the King (or Queen). The right test answer matches that.

The wrong answer choices each substitute a different anthem or song. The first choice is the NATIONAL anthem — proclaimed 1980 — not the Royal Anthem. The third choice is a different patriotic song, not the named Royal Anthem. The fourth choice is a British patriotic song, not the named Royal Anthem of Canada. Only God Save the King (or Queen) — the source's exact named Royal Anthem — matches.
