An office or position which is unfilled or unoccupied is called a:

• A. Open seat
• B. Vacancy
• C. Open position
• D. Vacant post

Answer: (B)

An unfilled or unoccupied office is described as a vacancy. In parliamentary procedure, vacancy is the precise noun used to denote a position that needs to be filled, and it’s the term you’ll see in motions and agendas, such as “to fill the vacancy” or “the vacancy exists.” The other phrases are less formal or more everyday language—open seat and open position are casual terms, while vacant post is less standard in procedural wording. Remember that vacancy is the noun form; the seat itself would be described as vacant.
