Answer:
B. During World War II the relocation was justified as a "military necessity."
Step-by-step explanation:
From the excerpt provided, the passage mentions that justifies the relocation as a "military necessity". This sentence alone is a good enough support for the research that gives reasons for the internment of Japanese-Americans.
Internment can be described as a a state or condition where people are confined without any charges or intent on making charges by a governing authority. It could be for political or military reasons, though there are no trials involved. It is mainly used for those people from other countries which are deemed as enemies at times of war. So, when the passage talks of how the government justified the relocation of these enemy citizens as a military necessity, it is a perfect example and support for the case of internment of the Japanese-American people.
