Best answer
Correct option is (a) fixed during sizing

The explanation: Thrust will be fixed during sizing if fixed engine is used. Fixed engine is any existing engine that is available for use. However, when we use fixed engine we are bounded with some constraints such as fixed thrust. Hence, we cannot vary thrust as a rubber engine.
