Answer:
Step-by-step explanation:
In the former case that is investment in security that pays interest of 8% per year for the next 2 years , there is provision of fixed interest rate . That means one can be assured of interest rate of 8 % for two years but he can not get benefit of market fluctuation if interest rate if it rises above 8 % after one year .
In case of investment in security that matures in 1 year but pays only 6% interest , one can take the benefit of market fluctuation if interest rate rises above 8 % . So if there is likelihood that interest rate can rise above 8 % in future , one should invest in 6% security for one year and reinvest it after one year , in the same security or in other security which fetches higher rate of interest .
Apart from that , if there is a contingent liability of paying after one year , one can not go in for 2 year security as it will have to break prematurely , that will result in loss of interest .
So due to situation described above, one should prefer investment in one year security .
