Correct Answer: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

Solution : The correct answer is (b) Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

The assertion that a large segment of the workforce continues to depend on primary activities to make a living is true, as many individuals in India are employed in agriculture, fishing, mining, and other primary sectors.

However, the reason provided, stating that trade, commerce, banking, tourism, and related services are developing faster than production activities, does not necessarily explain why a large segment of the workforce depends on primary activities. The reason does highlight the growth of these sectors in India, but it does not directly correlate with the dependence on primary activities for livelihood.

In summary, both the assertion and reason are true, but the reason does not provide the correct explanation for the assertion.
