b. 1941
c. 1945
d. 1948

Answer 1

Hint:
Japan finds a golden opportunity after the sudden collapse of France in June 1940 to exploit French defeat and remove several obstacles to its New Order in East Asia.


Complete solution:
In 1940, Germany defeated the French Third Republic and French Indochina's colonial administration passed to the French State. Tokyo decided to strengthen its position and at first Japanese troops entered parts of Indochina in September 1940. Japan extended its control totally over the French Indochina in July 1941. After seeing Japanese expansion over Indochina, President Franklin Roosevelt seizes all Japanese assets in the United States. He started pulling embargoes on exports of steel and oil to Japan from July 1940. To escape these embargoes and to become self-sufficient in resources, Japan decided to attack the British Empire and simultaneously the USA on December 7, 1941. In return, the USA declared war against Japan on December 8, 1941. At that time the British Empire was at war since 1939 with Germany. The US joined the British Empire and its existing allies in the fight against the Axis Power.
Additional information: Vichy, the common name of the French state signed the protocol concerning Joint Defence and Joint Military Cooperation. The protocol was signed on July 29. This agreement defined the relation between France and Japan for Indochina. It defines the relationship until the Japanese abrogated it in March 1945. In return for a fragile French autonomy, it gave a total of eight airfields. It also allowed them to have more troops present. It also allows them to use the Indo-Chinese financial system.


Hence, the correct answer is option B.

Note:
Japanese troops entered Indochina to strengthen its position after the discomfiture of the French Third Republic and French Indochina’s colonial administration passed to the French state.
