The correct answer is C) Germany infiltration of Belgium.
The event that accurately reflects the reason Great Britain joined the Allied Forces was Germany infiltration of Belgium.
Great Britain protected Belgium. Belgium’s ports were strategical for the national interest of England. When Germany infiltration of Belgium happened, this motivated Great Britain to join forces with France and Russia to form an Allied Forces front.
