A:A put option on a bond is a provision that allows the holder of the bond the right to force the issuer to pay back the principal on the bond. A put option gives the bond holder the ability to receive the principal of the bond whenever they want before maturity for whatever reason. If the bond holder feels that the prospects of the company are weakening, which could lower its ability to pay off its debts, they can simply force the issuerer to repurchase their bond through the put provision.
