Which right does a guardian have control over concerning the Ward's residence?

The correct choice is the right to change the Ward's address. A guardian has a legal responsibility to make decisions on behalf of their ward, particularly concerning their living situation. This often includes the authority to manage where the ward resides, which could involve relocating them to a more suitable environment for their needs.

Such decisions are taken with consideration of the ward's best interests, and the guardian must ensure that any changes in residence promote their ward's safety, health, and overall well-being. The guardian's role is to protect and care for the ward, and part of that entails making informed choices about their living conditions.

In contrast, while the other options deal with various rights related to autonomy and personal choice, they do not align with the specific authority bestowed upon a guardian regarding residency. The right to live independently and the right to choose the location suggest a level of autonomy that may not be feasible depending on the ward’s circumstances. The notion of abandonment is also fundamentally contrary to the guardian's responsibilities, as guardians are meant to provide support and protection, not to allow for a ward to be left without care or oversight.
