The correct answer is D. All of these.
Government securities are debt obligations issued by a national government. They are considered to be very safe investments because the government has the power to tax its citizens to repay its debts.
Promissory notes, debentures, and bearer bonds are all types of government securities. However, bearer bonds are no longer issued by the U.S. government.
A promissory note is a written promise to pay a certain amount of money on a specified date. A debenture is a type of bond that is not secured by any specific asset. A bearer bond is a type of bond that is not registered in the name of the owner, and the owner is the person who physically holds the bond.
The U.S. government currently issues three types of government securities: Treasury bills, Treasury notes, and Treasury bonds. Treasury bills are short-term securities with maturities of one year or less. Treasury notes have maturities of two to ten years. Treasury bonds have maturities of more than ten years.
Government securities are considered to be very safe investments because the government has the power to tax its citizens to repay its debts. However, government securities are not without risk. The value of government securities can fluctuate based on changes in interest rates.
