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)

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.
