African American youths were arrested.

Explanation:

The immediate response to the Wilmington high schools’ boycotts in 1971 was that "African American youths were arrested."

Following the Wilmington high schools’ boycotts in 1971, 10 civil rights activists were wrongly arrested, found guilty, and eventually imprisoned for about ten years.

These 10 civil rights activists include eight African American high-school students, an African American minister, and a white female social worker.

Hence, in this case, the correct answer to the question is "African American youths were arrested."
