which of the following administers licenses and registration to research facilities?

The entity that administers licenses and registration to research facilities is the Animal and Plant Health Inspection Service (APHIS) of the U.S. Department of Agriculture (USDA). APHIS is responsible for enforcing the Animal Welfare Act (AWA) and requires research facilities using regulated animals to be registered or licensed with it. APHIS conducts inspections to ensure compliance with the AWA regulations. Other entities like FDA regulate drug safety but the licensing and registration of research facilities falls under APHIS jurisdiction.
