The correct choice is California Department of Health Services. This agency is responsible for overseeing public health programs and ensuring the health and well-being of the residents in California. It plays a vital role in health policy, disease control, and health education, thus forming an essential part of the state's health infrastructure.

Other options represent real departments but do not refer to the correct title of the agency in question. For instance, while California may have a Department of Human Services dealing with social services, it does not correspond to health-related oversight. The mention of "Hospitals" or "Healthy" in the incorrect options could create confusion, but they pinpoint other types of services that the correct agency does not specifically handle. Therefore, knowing the precise title is crucial for understanding the role and function of the organization.
