Given the simple radial system below, if Z_line has an angle of 80° and Z_load has an angle of 10°, which of the following statements is false?

A) As Z_load increases, P_r increases rapidly at first and then slowly before reaching a maximum, and finally decreases.
B) The power transmitted is maximum when the voltage drop in the line is equal in magnitude to V_r.
C) The maximum value of P_r can be increased by increasing the voltage source E_s and/or decreasing Φ.
D) If P_r is greater than the maximum power, an increase in load admittance would increase power.
