A building jointly owned is called office________.

The correct answer is: B. condominium.

A condominium is a type of real property in which individual units are privately owned and common areas are jointly owned by the unit owners. Condominiums are often used as residential housing, but they can also be used for commercial purposes.

The other options are incorrect for the following reasons:

• Option A, “layout”, is not a type of real property.
• Option C, “accommodation”, is a general term for a place to stay, such as a hotel or a bed and breakfast. It does not specifically refer to a type of real property.
• Option D, “location”, is a general term for the place where something is situated. It does not specifically refer to a type of real property.

I hope this helps! Let me know if you have any other questions.
