AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
(A) Both A and R are true, and R is the correct explanation of A.
The government provides roads, bridges, schools etc. because private enterprises, driven by profit motive, will not invest in services that are necessary but do not yield high returns.
The textbook (Chapter 2) clearly states: "There are several things needed by the society as a whole but which the private sector will not provide at a reasonable cost" — directly supporting both A and R. R correctly explains why the government steps in, making option (A) the right choice. Remember: for R to be the "correct explanation," it must directly justify the assertion, not just be independently true.
