Step 1: Understanding unconventional superconductivity. - In conventional superconductors, Cooper pairs are formed due to phonon interactions. - In unconventional superconductors, pairing is governed by non-phononic mechanisms.
Step 2: Selecting the correct option. Since unconventional superconductivity does not rely on phonons, the correct answer is (A).
