What feature of a building can help manage water flow?

The choice that indicates all of the provided options—gutters, fascia, and eaves—plays a role in managing water flow is indeed the correct answer. Each of these elements contributes to directing rainwater away from the structure, which helps prevent water damage, erosion, and other related issues.

Gutters are channels installed along the roof edge to collect rainfall and direct it down through downspouts, effectively guiding water away from the building's foundation. This prevents pooling of water around the base, which can lead to structural problems over time.

Fascia boards, which are mounted along the roofline, support the gutters and provide a surface for them to attach. While their primary function is to serve as a finishing edge, they also help protect the roof and the inner workings of the building from moisture that may seep in if gutters are not properly maintained.

Eaves are the lower edges of a roof that overhang the walls of the building. They help to direct rainwater away from the building's siding and foundation, reducing the risk of water intrusion and helping protect the materials from rot and decay.

By incorporating all three components, a building can effectively manage water flow, safeguarding it from potential water-related damage.
