Which statement correctly defines 'migration' in a broad sense?

• A. The movement of people or animals from one region to another, based on a variety of different reasons
• B. The act of arriving late to work
• C. A form of energy transfer
• D. A religious ritual

Answer: (A)

Migration is about moving across space from one region to another, and it applies to both people and animals. It covers a variety of reasons for this movement—economic opportunities, environmental changes, seasonal patterns, breeding needs, or political or social factors—so the idea is broad and flexible. The best statement captures this broad sense by describing movement between regions and acknowledging multiple possible motivations.

The other options describe things that aren’t about relocating across places: arriving late to work is lateness, energy transfer belongs to physics, and a religious ritual is a ceremonial activity.
