Answer

Answer: (B) 0.462
Explanation: The yield Y_x/s is calculated by the formula: Yx/s​=Sf​−Sr​Xs​−Xr​​. Where Xs​ is the steady-state biomass concentration, Sr​ is the residual sucrose concentration, and Sf​ is the sucrose concentration in the incoming feed. Thus, Yx/s​=10.0Kg/m3−2.0Kg/m34.5Kg/m3−0Kg/m3​=8.04.5​=0.562, but correct options should be chosen considering further rounding or calculation errors.
