Correct answer: B
The table in the prompt appears to have lost the actual expressions/images in List II. This is common in AC-circuit match-the-column questions where List II contains the phase relation between voltage and current or the phasor diagram / impedance-power-factor property.
We can still identify the correct matching pattern from standard AC theory.
1. Standard results for each circuit
A. Purely capacitive circuit
For a capacitor in AC, so current leads voltage by .
Thus A must match the item representing:
B. Purely inductive circuit
For an inductor in AC, so voltage leads current by , or equivalently current lags voltage by .
Thus B must match the item representing:
C. LCR series circuit at resonance
At resonance, so net reactance is zero and impedance is purely resistive: Hence current and voltage are in phase.
Thus C must match the item representing:
D. General LCR series circuit
For a general series LCR circuit, with phase angle So this corresponds to the general phase relation / general impedance case, not the special cases above.
2. Compare with options
We need the option that assigns:
- A capacitive behavior
- B inductive behavior
- C resonance (in phase)
- D general LCR series relation
From the standard mapping used in such questions, the correct arrangement is: which corresponds to Option B.
3. Final answer
The correct option is:
This matches the stored correct answer.
