Concept:Economics is treated as a science because it applies systematic and scientific procedures to study economic behaviour.
Explanation:Scientists rely on observation, hypothesis formulation, testing, and verification.
Economics similarly observes economic events and builds theories based on evidence.
It also makes use of data collection, analysis, and logical reasoning to explain and predict human choices.
Therefore, although economics deals with human behaviour, it is called a science because it adopts scientific methods in making its analysis.
Option A is not fully correct because economic issues cannot always be easily verified by facts due to changing human behaviour.
Option C merely states its usefulness, not its scientific nature.
Option D only suggests that its subject matter is human behaviour, which alone does not make it a science.
Answer:B. it adopts scientific methods in making its analysis
