The transistor shunt regulator shown in the figure has a regulated output voltage of 10 V, when the input varies from 20 V to 30 V. The relevant parameters for the zener diode and the transistor are: V_Z = 9.5, V_BE = 0.5 V, β = 99. Neglect the current through R_B. Then the maximum power dissipated in the zener diode (P_Z) and the transistor (P_T) are

A. P_Z = 75 mW, P_T = 7.9 W

B. P_Z = 85 mW, P_T = 8.9 W

C. P_Z = 95 mW, P_T = 9.9 W

D. P_Z = 115 mW, P_T = 11.9 W
