Which failure mode occurs most rapidly when Inca rope suspension bridge cables become persistently waterlogged?

A)Microbial cellulose degradation
B)Elastomeric fiber disentanglement
C)Progressive creep deformation
D)Accelerated cable oxidation

💡 Explanation

Increased saturation causes microbial cellulose degradation via enzymatic action because moisture fosters microbial growth within the rope fibers, therefore material strength declines faster; rather than oxidation/creep, which are slower than biological decomposition in this setting.
