What is the main function of a guardian in relation to a ward?

The primary role of a guardian is to ensure the well-being and care of their ward, which includes managing the ward's personal affairs and property. This encompasses not just financial management, but also promoting the ward's best interests in various aspects of life, including health care, education, and personal welfare. A guardian acts on behalf of the ward, making decisions that affect their daily life and legal matters, thus taking on responsibilities that cover both personal care and asset management.

While there may be other roles associated with a guardian, such as overseeing social interactions or providing legal representation as needed, those are secondary to the overarching responsibility of caring for the ward and managing their affairs. Therefore, the choice identifying the guardian's main function accurately reflects the comprehensive nature of this role.
