Which act defined the services to be provided for children's services in England?

The Children Act 1989 is pivotal in shaping the framework for children's services in England. It was introduced to ensure the welfare and safety of children by establishing a comprehensive legal structure for local authorities, social services, and various organizations involved in the care and protection of children. This act introduced principles that prioritize the child's best interests, which are fundamental to any intervention involving minors.

It mandated that local councils must provide services to support children and their families and set clear guidelines on how to assess children in need. The act also provided the legal basis for creating a system of child protection, ensuring that children are safeguarded from harm.

In contrast, the other options either do not specifically focus on children's services or relate to different aspects of health and social care. The Children Act 2010 builds on previous legislation but does not primarily define services, while the Community Care Act 1990 and Health and Social Care Act 2006 address broader issues in health and social care, rather than specifically targeting children's services.
