Which of the following statements about theories of the yield curve is most likely correct？（)

A.A liquidity preference is not consistent with a flat term structure of interest rates.

B.The pure expectations theory suggests that an upward-sloping term structure of interest rates is a consequence of investors expecting short-term rates to remain unchanged for a period of time, followed by investors expecting short-term rates to rise for a period of time.

C.The liquidity preference theory suggests that a downward-sloping term structure of interest rates is due to declining expected short-term rates, and although there is a maturity premium to consider, it is not large enough to offset the expected decline in short-term rates.
