C) 300 V
D) 344 V

Voltage Drop

The reduction in voltage across a component or conductor due to resistance or impedance within the circuit.

RLC Series Circuit

A circuit consisting of a resistor (R), inductor (L), and capacitor (C) connected in series, affecting the impedance and phase of the circuit.

Final Answer :
C
Explanation :
The voltage drop across the inductor can be calculated using Ohm's Law (V = IZ), where I is the current in the circuit and Z is the impedance of the inductor. First, find the total current in the circuit using the total impedance (Z = 80 Ω) and the applied voltage (V = 240 V). The current I = V/Z = 240 V / 80 Ω = 3 A. The voltage drop across the inductor (VL) is then calculated using the inductive reactance (XL = 100 Ω) and the current (I = 3 A), so VL = IXL = 3 A * 100 Ω = 300 V.
