Explanation: Minimizing the transfer of harmonic frequencies between inductively coupled circuits typically involves selective filtering. A low-pass filter, for instance, is designed to pass the desired fundamental frequency while attenuating higher-frequency harmonics. Alternatively, proper tuning of the resonant circuits can maximize transfer at the fundamental while minimizing it at harmonic frequencies. Option B, "Induces magnetic shielding between two coils," would reduce *all* inductive coupling (both fundamental and harmonics) by blocking magnetic field lines, rather than selectively minimizing harmonics while preserving the fundamental. Option C, "Transfers energy between two coils," describes the very purpose and action of inductive coupling, not a method to minimize unwanted harmonic transfer. Since specific techniques like filtering or selective tuning are not listed, D, "None of the above," is the correct answer.
