Frequency affects only on inductor XL = 2Pifl in a resistor frequency doesn't affect. If frequency increases VL is greater.

If frequency increases, inductance increases.

Inductive reactance is directly proportional to frequency xl = 2 * 3.142 * f * l(xl=f).

As we know Xl=2*pi*f*L. So when f will increase Xl increases and voltage drop through inductance increases (Vl=I*Xl). So Vl must be greater than Vr.

When the frequency is increased then the impedance X(L) increases and the drop VL across the inductor increases as compared to VR across R.

As we know that xl=f, so increasing frequency, inductance voltage increase also vl>vr.

Xl=2*Pi*f*L, with increase in reactance, voltage is supposed to increase. The correct option can be D. If anyone has alternative please reply.

With frequency increasing, reactance supposed to be increased as well, it means the right answer is option D.
