CAP is a crucial infrastructure for which of the following purposes?

The Central Arizona Project (CAP) is an essential infrastructure system primarily designed for the transport of Colorado River water to central and southern Arizona. It serves as a critical water supply source for urban areas, agricultural lands, and various industries in the region, effectively managing Arizona's water resources amidst limited availability.

While the CAP does indeed support urban development and agricultural irrigation indirectly by providing much-needed water, its primary function is the transportation of Colorado River water. This infrastructure includes an extensive canal system that runs over 300 miles, directing water from the river into reservoirs and distribution systems for use in farming and urban areas.

The alternative options mention flood prevention and urban development support, but these are not the principal purposes of the CAP. Flood prevention typically involves a different set of infrastructure and management practices, while urban development relies on water availability rather than the transport itself being the aim of the project.
