Rainbow, you have to do nothing else than to realize how the current(s) - driven by the voltage source - will flow through the various components.
That means: Will there be two currents (in parallel)? And will this current (or both of them) flow through any series connection?
I think, the answer is simple, is it not?
The capacitor and the 8 Ohm resistor are connected in series. Call this Z!. The Inductor and the 4 Ohm resistor are connected in series. Call this Z2. Z1 and Z2 are connected in parallel. This is in agreement with the "current splitting" rule suggested by LvW, xharu2539211 and chri$.
