Answer:
O It includes firsthand interviews with relocated Japanese Americans.
Explanation:
A primary source is a source that contains either a first-hand account of the event or any source created at the time of the event. The word "primary" means that is genuine and provides the best and most truthful version of the event(s).
For a source to be considered 'primary' in nature, it has to contain details that tell the most truthful and original information. It should not be revised, or copied, or reproduced from a source.
So, the Japanese Relocation video can be considered a primary source because of the fact that it contains firsthand interviews with the relocated Japanese Americans. By hearing about the historical event from the ones present during that time, the information can be deemed genuine and valid.
Thus, the correct answer is the second option.
