For the n-channel MOS transistor shown in the figure, the threshold voltage VTh is 0.8 V. Neglect channel length modulation effects. When the drain voltage VD = 1.6 V, the drain current ID was found to be 0.5 mA. If VD is adjusted to be 2 V by changing the values of r and VDD, the new value of ID (in mA) is |

B. | 0.75 |
C. | 1.125 |
D. | 1.5 |
