AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The correct answer is B.
Non-mechanised sectors remained significant because small innovations (e.g., in food processing, pottery, furniture making) drove their independent growth, and new technology was expensive, slow to adopt, and less effective than claimed, leaving traditional industries competitive.

The passage explicitly states: "small innovations were the basis of growth in many non-mechanised sectors such as food processing, building, pottery, glass work." It also notes new technology was expensive and slow to be accepted. Option A is false (no such ban existed); C is unsupported; D is contradicted by the text, which says these industries "did not remain entirely stagnant." Examiners expect you to identify the option directly supported by the source.
