Explanation
Answer - A - The immediate cause for the United States entering World War I was Germany’s announcement that they would use unrestricted submarine warfare.

Key Takeaway: Ultimately, it was Germany’s announcement that it would return to completely unrestricted submarine warfare that led the United States to enter World War I.
