Which group cooperated with revolutionaries after Aguinaldo's return from Hong Kong and actively participated in the Filipino-American War?

• A. Visayans
• B. Ilocanos
• C. People of Negros
• D. Muslims

Answer: (C)

Regional groups across the islands stepped up to support the revolutionary cause after Aguinaldo’s return, and the People of Negros were especially active. They organized locally, formed forces, and fought alongside the revolutionary movement against American forces, becoming a key base of resistance in the Visayas. Leaders from Negros mobilized fighters and resources, including sugar planters, to arm and sustain the struggle, contributing directly to the Filipino–American War. This strong, organized participation distinguishes Negros as the group most clearly associated with cooperating with the revolutionaries during that period.
