What is your reason for choosing this type of government bond?

Government bonds are debt securities issued by the government, either bonds with fixed interest or types of bonds with interest that changes according to the market. The main purpose of these bonds is as a source of funds for the government to carry out projects or development. Many investors choose this type of government bond because it has low risk. However, you should not only rely on low risk, but of course there are factors that you need to consider as your reason for choosing government bonds.

I am not into government bond. Although it's good because it has low risk but I not familiar of this and dunno the right agency in my country responsible to this.

You will have to see where the money will be used. If the government plans to raise funds to finance projects that will take a long time to give returns, your investment can be at risk.
