Answer:
The correct option is D,the markets for bonds of different maturities are separate or segmented
Explanation:
Market segmentation theory is of the view that market for short-term and long-term bonds are segmented from each other,wherein investors with different preferences investing in different markets.
Banks for instance are short-term position takers due to their preference for liquidity and would favor investing short-term instruments like the 3-month Treasury bill such that at every point in time, there is enough cash liquidity to meet customers' request for withdrawal of funds.
On the flip side, pension fund administrators take a long-term position on investment, hence would prefer the 30-year Treasury bill since their payment of retirement benefits is usually a low portion of their total contributions received from contributors to their pension funds.
