Explanation:

- Option 1: Australia

- In February 2023, Australia announced that it would remove the British monarchy from its banknotes. Instead, they planned to feature an Indigenous design for its $5 note.

- The decision reflects a move toward acknowledging Indigenous culture and history.

- Option 2: Nepal

- Nepal does not have British monarchy representations on its currency, so no recent announcements were necessary.

- Option 3: Sri Lanka

- Sri Lanka has its own distinct currency design and no recent shifts involving the British monarchy on its notes.

- Option 4: Canada

- While Canada has connections to the British monarchy, there were no announcements in February 2023 about changing currency designs to remove such imagery.
