Which outcome occurs when Inca suspension bridge fiber ropes experience repeated wetting and drying cycles?

💡 Explanation

Inca suspension bridges suffered accelerated degradation because microbial cellulose digestion of the plant fiber material increased during the frequent wet/dry cycles; this enzymatic decomposition degraded the structural integrity, therefore option A is correct rather than enhanced alignment or polymer annealing.
