A series RLC circuit is driven at a frequency equal to 0.70 f0, where f0 is its resonant frequency. Which statement is correct about the reactances at this driving frequency?
a) XL>XC ; the circuit behaves inductively
b) XL<XC ; the circuit behaves capacitively
c) XL=XC ; the circuit is purely resistive
d) XL<XC ; the circuit behaves inductively
