Explanation

Aerial pathways - cables routed overhead, typically along poles or the exterior of buildings - are quick to install (A) because they require no trenching, tunneling, or penetration of walls, and they are readily accessible for maintenance (E) because the cabling remains visible and reachable without excavation or disassembly. Option B is wrong because aerial installations often require poles, brackets, and weatherproofing hardware that drive up upfront costs. Option C describes a disadvantage, not an advantage - overhead cabling is widely considered an eyesore that detracts from a property's appearance. Option D is wrong because aerial cables are exposed to UV, wind, ice, and moisture, which degrades them faster and raises long-term maintenance costs compared to protected underground routes.

Memory tip: Think "up and at 'em" - aerial pathways go UP fast (quick to install) and stay UP where you can easily reach them (accessible for maintenance). Everything else - cost, looks, longevity - works against them, not for them.
