The propulsive efficiency of a ramjet engine is lower than that of a low bypass turbofan engine operating under the same conditions and producing the same thrust, primarily because the ramjet engine
(A) has larger kinetic energy lost in the exhaust jet.
(B) has lower thrust power.
(C) is not self-starting.
(D) has higher thrust to weight ratio.
