This funding is to determine the need, engineering feasibility, and economic and engineering return to the Nation, of potential solution to water and related land resource problems for specifically authorized projects.

• A. Investigations
• B. Construction
• C. Operations and Maintenance
• D. Research and Development

Answer: (A)

The key idea here is the planning phase that validates a project before anything is built. Investigations involve studies to determine whether there is a real need, assess engineering feasibility, and evaluate the economic and engineering returns to the Nation for proposed water and land-resource solutions. This upfront work justifies and shapes any authorized project, laying out options, benefits, and costs so a decision can be made about moving forward. Construction would come later, after approval, to actually build the project. Operations and Maintenance deal with running the project once it's built, and Research and Development focuses on new methods and technologies, not on evaluating a specific proposed project’s viability.
