A)the turbine work output will increase.
B)the amount of heat rejected will increase.
C)the cycle thermal efficiency will decrease.
D)the quality of steam at turbine exit will decrease.
E)the amount of heat input will decrease.

With ideal regeneration, some steam is extracted from the turbine to preheat the feedwater, reducing the amount of heat required from the boiler, thus decreasing the heat input per unit mass of steam.
