Answer» The correct OPTION is (c) LC IMPEDANCE To explain: The singularity nearest to ORIGIN is a zero. So it may be RL impedance or RC admittance function. Because of (D) option it is required to CHECK that it is a valid RC admittance function. The poles and ZEROS interlace along the negative real axis. The residue of Yrc(s)/s is positive.
