Two statements are given, one is labelled as Assertion (A) and the other as Reason (R):
Assertion (A): In post Independence period, the state assumed that operating in a caste-blind manner would automatically lead eventually to the abolition of the institution of caste.
Reason (R):  Modern industry created all kinds of new jobs for which there were no caste rules.

Both (A) and (R) are true and (R) is not the correct explanation for (A)

The correct answer is Option 2: Both (A) and (R) are true and (R) is not the correct explanation for (A).

Assertion (A): "In the post-Independence period, the state assumed that operating in a caste-blind manner would automatically lead eventually to the abolition of the institution of caste." — Correct. After Independence, the state believed that treating citizens without reference to caste in most areas of governance would gradually weaken caste-based privileges and lead to the eventual decline of the caste system.

Reason (R): "Modern industry created all kinds of new jobs for which there were no caste rules." — Correct. The growth of modern industry introduced occupations that were not governed by traditional caste-based occupational restrictions. These new employment opportunities reduced the direct link between caste and occupation.

Why is (R) not the correct explanation for (A)? The Assertion refers to the state's approach towards caste and its policy assumption, whereas the Reason explains how economic change and industrialization indirectly affected caste by creating new occupations. Although both statements are true and relate to social change after Independence, the creation of new industrial jobs does not explain why the state adopted a caste-blind approach.

NCERT: On the one hand, the state was committed to the abolition of caste and explicitly wrote this into the Constitution. On the other hand, the state was both unable and unwilling to push through radical reforms which would have undermined the economic basis for caste inequality. At yet another level, the state assumed that if it operated in a caste-blind manner, this would automatically lead to the undermining of caste based privileges and the eventual abolition of the institution.  The development activity of the state and the growth of private industry also affected caste indirectly through the speeding up and intensification of economic change. Modern industry created all kinds of new jobs for which there were no caste rules.
