Final answer:
A Maryland condominium declaration can be changed only with the unanimous approval of the council of unit owners.
Step-by-step explanation:
The correct option is C) It can be changed only with the unanimous approval of the council of unit owners.
A Maryland condominium declaration is a legal document that outlines the rights and responsibilities of unit owners in a condominium complex. It can be amended or changed, but any changes require the unanimous approval of the council of unit owners, which represents all the unit owners in the complex.
For example, if there is a need to change a certain rule or regulation in the condominium declaration, such as parking regulations or pet policies, the unanimous approval of the council of unit owners is required to make those changes.
