Concept:Economics is called a science because it applies scientific methods to study real-world economic behaviour.
Explanation:Science involves systematic observation, data collection, and theory building.
Economics uses these scientific methods to develop theories that explain observed phenomena in human behaviour.
It does not mainly depend on laboratory experiments or controlled experiments because human actions are complex and difficult to isolate.
Although economics makes predictions, such predictions are not always perfectly accurate for every individual.
Therefore, the scientific nature of economics lies in its method of explaining observations, not in exact prediction or lab testing.
Answer:B. uses scientific methods to explain observed phenomena.
