Final answer:
The best description for wood ladders among the given options is Option C: Wood ladders offer better resistance to flexing and bouncing when being climbed.
Step-by-step explanation:
This is because wood ladders have a certain amount of flexibility that allows them to withstand the weight of a person climbing on them without breaking or collapsing. Wood ladders are also less likely to bounce or sway when being climbed, providing a more stable and secure experience for the user.
While other options like being light and easy to handle (Option A) or having the lowest cost (Option B) may also be true for some wood ladders, they are not the defining characteristics that set wood ladders apart from other types of ladders.
Option D is incorrect because wood ladders do not fail suddenly when exposed to a specific temperature. Heat can weaken the structural integrity of wood, but it generally takes a gradual increase in temperature to cause significant damage or failure.
