Humanitarian aid can serve as a tool of foreign policy by fostering positive attitudes toward the donor country.

This goodwill can lead to stronger diplomatic relations, increased cooperation on mutual interests, and support for U.S. policies in international forums. Therefore, option A) aligns with how humanitarian aid can support broader foreign policy goals.
