Treasury securities (Treasury bills, notes, and bonds) are obligations of the U.S. government. A key testable feature is their tax treatment: interest earned on Treasuries is subject to federal income tax (though it is generally exempt from state and local income taxes). That makes choice B correct.
Choice A is incorrect because FDIC insurance applies to bank deposit products (e.g., bank CDs, savings accounts) held at insured depository institutions, within insurance limits. Treasury securities are not bank deposits; they are direct government securities, so “FDIC-insured” is not the right concept. Treasuries are considered to have very low credit risk due to U.S. government backing, but that is different from FDIC insurance.
Choice C is incorrect because Treasuries trade in both the primary market (when issued by the Treasury) and the secondary market (after issuance). In fact, Treasuries are among the most actively traded securities in the world, and secondary-market trading is a major source of liquidity and price discovery. Investors can buy newly issued Treasuries at auction (primary) or purchase existing Treasuries from other investors and dealers (secondary).
Choice D is incorrect because securities issued by states and municipalities are municipal securities (muni bonds/notes), not Treasury securities. Treasuries are issued by the U.S. Department of the Treasury, while municipal bonds are issued by states, cities, counties, and other political subdivisions or authorities.
On the SIE, this question targets product knowledge: issuer identity, trading markets, and tax characteristics of government vs. municipal vs. bank products.
