Answer:
(C) The liquidity hypothesis indicates that, all other things being equal, longer maturities will have higher yields.
Explanation:
As per the expectation theory the inflation is also considered while computing the related return. Accordingly in the long run when costs increases due to inflation, the expected return is also meant to increase as every individual investor not only aims to get return but to get a return which provides gain, and surety of covering all the costs.
Accordingly in long term maturities the yields will be higher.
