What is one responsibility of a guardian of the person?

The responsibility of a guardian of the person fundamentally centers around acting in the best interest of the minor. This role entails making decisions that prioritize the child's physical, emotional, and educational well-being. The guardian must consider the minor's needs and desires, aiming to provide a stable and supportive environment. This involves a comprehensive approach to care, which can include healthcare decisions, education, and everyday welfare.

In this context, the other options do not accurately reflect the primary responsibilities of a guardian. For instance, ensuring unlimited visitation rights for parents may not serve the child’s best interests, especially if the visitation could be harmful. Providing financial assistance exclusively overlooks the broader spectrum of care that the guardian must engage in, which goes beyond just financial support. Reporting a minor's progress to the court could be a component of a guardian's duties, especially if mandated by court orders, but it is not as fundamental as the overarching responsibility to act in the child's best interest. Thus, the correct choice truly encapsulates the essence of a guardian's role.
