Answer:
c. bureaucracy
Step-by-step explanation:
The system of California leaders who carried this work is a bureaucracy because they are people who belong to government agencies, but perform technical and skilled jobs (the kind of job needed for building a proposal to build a water canal) that do not necessarily depend on the political authority of a specific period.
In other words, bureaucrats are members of government agencies whose skills are valuable, and for that reason, most of them keep their jobs under different political administrations.
