Who represents the Sovereign in each of Canada's ten provinces?

Discover Canada records this in one direct sentence. The guide writes: In each of the ten provinces, the Sovereign is represented by the Lieutenant Governor, who is appointed by the Governor General on the advice of the Prime Minister, also normally for five years. The role the test wants is therefore the Lieutenant Governor.

The pairing with the federal level is built into the same passage. Discover Canada writes earlier in the same paragraph that "the Sovereign is represented in Canada by the Governor General, who is appointed by the Sovereign on the advice of the Prime Minister, usually for five years." So at the federal level, the representative is the Governor General; at the provincial level, the representative is the Lieutenant Governor. The structures are deliberately parallel.

Each Lieutenant Governor has a constitutional role inside the provincial legislature. Discover Canada writes: "Provincial legislatures comprise the Lieutenant Governor and the elected Assembly." So the Lieutenant Governor is one of two parts of a provincial legislature, alongside the elected Assembly — the provincial parallel of the Sovereign-plus-chambers structure at the federal level.

Appointment goes through the federal Governor General. Discover Canada's key line: "appointed by the Governor General on the advice of the Prime Minister, also normally for five years." That arrangement keeps the office connected to federal government while still rooting it in the province it represents.

The question is testing whether new citizens know the provincial parallel of the federal Governor General. Discover Canada commits to one role: the Lieutenant Governor. There is one such office in each of the ten provinces.

The wrong answer choices each pick a different role. The Prime Minister is head of the federal government, not a provincial representative of the Sovereign. The Provincial Premier is the head of a provincial government — political, not constitutional-representative of the Sovereign. The Governor General represents the Sovereign at the federal level, not in each province.
