Answer:
The correct answer is option b.
Step-by-step explanation:
Positive economics is a branch of economics that is concerned with explanation of economic phenomena. It is based on facts and data. It answers to what is, what was.
Normative economics, on the other hand, is concerned with judgment. It answers to what should be or what ought to be.
Structural unemployment is caused because of a mismatch between the skills that the workers possess and the skills that the employers want.
Innovation and technological changes will always cause structural unemployment and create winners and losers. So the government should focus on helping the displaced workers in finding new jobs, instead of limiting innovation.
As this involves what should be done, it is a normative issue.
