AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.

The passage directly states: "In many industries the demand for labour was seasonal… industrialists usually preferred hand labour, employing workers for the season." The examiner expects you to link seasonal demand to the practice of hiring workers only for certain months. Options A, C, and D are not supported by the text — machines, government restrictions, or worker preference are not cited as reasons. Always base MCQ justifications on the source text.
