An alternating current (a.c.) voltage source at 50 Hz is applied to a series combination of resistor A of resistance ‘P' and component B of reactance ‘Y'. The phase angle is $+\pi/4$. Which of the following is true?
- (a)B is a capacitor and $Y = 2P$.
- (b)B is an inductor and $Y = 2P$.
- (c)B is a capacitor and $Y = P$.
- (d)B is an inductor and $Y = P$.
