In series RL circuit voltage increases as frequency decreases but voltage is directly proportional to current and hence the answer.

In series RL circuit current is varied corresponds to frequency.

In RL circuit there is a time required to reach maximum current, so the time increases frequency will be decreases.

Option A is correct answer. Voltage and frequency are directly proportional in inductive circuit. Voltage is directly proportional to current.

I = V/xL, I = v/wL it means, the current is inversely proportional to frequency.

As frequency decreases xl decrease so that net impedance 'z' decrease so that opposition to current flow decrease hence more current flow.

I = v/z.
I = 1/2 * π * f * l current increases the frequency decreases.
