Answer

a. Eddy currents ### d. Skin effect Explanation 1. Identify phenomena affecting cable choice at high frequency At high frequencies, skin effect and eddy currents cause current to concentrate near the conductor's surface, increasing resistance in solid wires. 2. Match options to relevant phenomena Skin effect (d) and eddy currents (a) are directly related; EMF and magnetic flux do not necessitate stranded cables.
