Which of the following describes a 'cessation'?

The term 'cessation' refers specifically to the act of stopping or bringing something to an end. Thus, when describing a 'cessation,' it signifies that there is a pause or a complete halt in activity, which aligns perfectly with the meaning of 'cessation.'

In contrast, the other choices imply continuity: a continued process suggests ongoing action, an ongoing activity reinforces that something is actively taking place, and a beginning of something new indicates the initiation of an event or process rather than its termination. These descriptions do not correspond to the concept of 'cessation,' which fundamentally centers on stopping or ending an existing activity.
