【正确答案】
A
【答案解析】The preferred habitat theory states that investors will move from their preferred maturity on the yield curve to another area on the yield curve to achieve higher yields. With the liquidity preference theory the yield curve can remain upward sloping even if short term rates are predicted to decline as long as the liquidity premium is sufficiently large. With the market segmentation theory the supply of bonds and demand for bonds at various maturities determine their yields and the resulting yield curve.
