Final answer:
The Royal Navy expelled Argentina from the Falkland Islands in 1833, and later during the Falklands War in 1982, British forces once again thwarted Argentina's attempt to reclaim these islands.
Step-by-step explanation:
In 1833, the Royal Navy expelled Argentina from the Falkland Islands. The Galápagos Islands are not the correct answer as they are known for their ecological significance and the development of Darwin's theory of evolution.
In 1982, almost 150 years later, Argentina attempted to reclaim the Falklands, leading to the Falklands War, where British forces once again ousted Argentina. Therefore, the correct answer to this historical question is B) Falkland Islands.
