Consider a simple ideal Rankine cycle with fixed boiler and condenser pressures. If the cycle is modified with regeneration that involves one open feedwater heater (select the correct statement per unit mass of steam flowing through the boiler),
(a) The turbine work output will decrease.
(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 increase.
