The correct statement is:
The business has federal tax exemptions.
A 501(c)(3) designation means that the organization is recognized as a nonprofit entity that is exempt from federal income tax and can receive tax-deductible charitable contributions. The other statements may not necessarily be true. For example, a 501(c)(3) organization can earn profits, but those profits must be used to further its charitable purposes. Additionally, a 501(c)(3) can be either a public charity or a private foundation, depending on how it is funded and operated.
