Which type of committee is specifically formed for a designated task and disbanded afterward?

The definition of an ad hoc committee is that it is established for a specific purpose or task and is dissolved once that task is completed. This type of committee is often formed to address unique or temporary issues that arise, such as planning an event, tackling a particular project, or conducting a special investigation. The temporary nature of ad hoc committees makes them distinct from other types of committees.

In contrast, an executive committee typically exists as a permanent entity, responsible for making decisions and managing the organization’s affairs on behalf of the larger board. This committee operates continuously and is involved in ongoing governance and oversight.

A standing committee, similarly, is one that is established on a permanent basis to handle recurring responsibilities and functions within an organization. Its purpose is ongoing, and it remains in place as long as its functions are needed.

A management committee generally focuses on the administrative and operational aspects of an organization and often has a continuous role, overseeing day-to-day activities and ensuring that the organization's objectives are met.

Thus, an ad hoc committee is the correct answer, as it is uniquely characterized by its temporary formation for a specific purpose, distinguishing it from the other types mentioned.
