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.
Resources contribute to development only when accompanied by appropriate technology, quality of human resources and institutional changes — which directly explains why resource-rich regions may still be economically backward.
The textbook explicitly states: "There are many regions in our country that are rich in resources but these are included in economically backward regions… resources can contribute to development only when they are accompanied by appropriate technological development and institutional changes." This means R directly and correctly explains A. Always check if the Reason logically causes/explains the Assertion — if yes, option (A) is correct.
