Which of the following is gilt-edge security?

Gilt-edge security refers to government bonds and stocks, which are considered to be low-risk and high-quality investments because they are backed by the government. These securities are generally considered to be very safe investments because they are based on the creditworthiness and stability of the government, which is expected to honor its obligations to pay interest and repay the principal on the bonds or stocks. Therefore, investors seeking low-risk investments often turn to gilt-edge securities.
