    Correct Option: (c)

    Explanation: Propellant flow is considered to be constant and steady in an ideal rocket. Along with the possible cut-offs in flow, such as shock waves, all types of boundary layers and frictional effects are neglected in such vehicles. The expansion of the working fluid is uniform as well as steady.
