Which risk increases when long undersea telecommunication cables experience seawater intrusion?

A)Increased signal attenuation losses
B)Elevated data encryption overhead
C)Reduced laser diode lifespan
D)Enhanced quantum entanglement fidelity

💡 Explanation

Seawater intrusion raises conductivity, which affects impedance matching for transmission lines; therefore, signal attenuation losses increase because electromagnetic energy is dissipated through dielectric losses, rather than increased quantum entanglement.
