In resistive region . . . . . . . . A. Vds greater than (Vgs – Vt) B. Vds lesser than (Vgs – Vt) C. Vgs greater than (Vds – Vt) D. Vgs lesser than (Vds – Vt)

The correct answer is: B. Vds lesser than (Vgs – Vt)

In the resistive region, the MOSFET is operating in the linear region. This means that the drain current is proportional to the gate-source voltage, and the drain-source voltage has little effect on the current. The drain-source voltage is therefore less than the gate-source voltage minus the threshold voltage.

Option A is incorrect because the drain-source voltage is less than the gate-source voltage minus the threshold voltage.

Option C is incorrect because the gate-source voltage is greater than the drain-source voltage minus the threshold voltage.

Option D is incorrect because the drain-source voltage is greater than the gate-source voltage.
