The answer is: C
Explanation
The correct option is C: rioting.
Explanation:
The use of violence by a member of an assembly of five or more persons in furtherance of a common object constitutes rioting. Rioting involves a tumultuous disturbance of the peace by a group of people assembled for a common purpose. It typically includes violent actions, such as assault, damage to property, or other disruptive behavior.
Affray generally refers to a public fight or brawl between two or more individuals that disturbs the peace, but it is not specifically related to a group or assembly.
Assault refers to intentionally causing apprehension of harmful or offensive contact, but it may not necessarily involve a group of people or a common object.
Unlawful assembly is the gathering of people with the intent to commit a crime or engage in violent activity, but it may not necessarily involve the actual use of violence.
Therefore, in the context described, the correct term for the use of violence by a member of an assembly of five or more persons with a common object is rioting.
