If your X is frequency invariant then it is a resistor.
If you have L C R in series (where R can be the resistance of the L),
then in resonance you will see R (real).
R also sets the Q factor of your series circuit, so its bandwidth.

thanks for your answer.
However, I beleive the job of the susceptance/reactance is to shift
the resonant frequency of the LC series from w = 1 to another
frequency, which denotes the transmission zero of the filter.

It's very difficult to understand the wording.
It is possible to drop the resonant frequency to say 0.5 Rads, using just a
resistance. Maybe that's what's wanted in this case.
