Answer (A) is correct. A short-term security issued by a corporation or agency created by the U.S. government, such as the Federal Housing Administration, is an agency security (agency issue). Among the largest issuers of agency securities (excluding the Treasury) are the Federal Home Loan Banks, the Federal National Mortgage
Association (Fannie Mae), and the other entities that provide credit to farmers and home buyers. Other issuers of home mortgage-backed securities include the Government National Mortgage Association (Ginnie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac).
