The correct answer is: C. Radial system
A radial system is a type of distribution system in which water flows from a central source to the outer periphery. This type of system is often used in urban areas, where there is a high demand for water. Radial systems are efficient and reliable, but they can be expensive to install.
A ring system is a type of distribution system in which water flows in a circular pattern. This type of system is often used in suburban areas, where there is a lower demand for water. Ring systems are less expensive to install than radial systems, but they are not as efficient.
A dead-end system is a type of distribution system in which water flows from a central source to a dead end. This type of system is often used in rural areas, where there is a low demand for water. Dead-end systems are the least expensive to install, but they are not as efficient as other types of systems.
A grid-iron system is a type of distribution system in which water flows in a grid pattern. This type of system is often used in commercial and industrial areas, where there is a high demand for water. Grid-iron systems are efficient and reliable, but they can be expensive to install.
