NoteThe source confirms that ARC is a non-profit organization, but it does not explicitly state the specific legal structure (501(c)(3) status). While the claim is plausible and the source is from ARC's official website, the source text provided does not contain the specific information needed to verify the 501(c)(3) designation. To confirm this claim, one would need to check IRS records, the organization's bylaws, or other official documentation that explicitly states the 501(c)(3) status.
