Which option correctly defines 'intervene'?

• A. To interrupt.
• B. To be situated between two things.
• C. To get involved or become involved in a situation in order to change its suspected outcome.
• D. To cease activity.

Answer: (C)

Intervene means to step in and take action in a situation in order to influence what happens next. It describes getting involved with the aim of changing the outcome, often to prevent harm, resolve a problem, or help others.

Interruption is about breaking a moment or activity temporarily, not about changing the overall course. Being situated between two things refers to physical placement, not action. Ceasing activity means stopping involvement, the opposite of taking action. So the statement that emphasizes getting involved to alter the outcome best captures the meaning of intervene.
