Which risk increases when a long undersea cable's insulation degrades?

💡 Explanation

Increased signal reflections at faults occur, because impedance mismatching increases due to localized shorting, thereby hindering signal propagation, rather than resonance shifts other phenomena. The mismatched impedance causes signal reflections.
