इस परिच्छेद से कौन-सा मुख्य विचार अनुगत होता है?

Correct Option: It is difficult, if not impossible, to repair every manifestation of historical injustice.

The passage discusses historical injustices such as untouchability, noting that they resist repair because their roots are deep, they constitute economic and ideological structures of exploitation, and they involve overlapping wrongs like economic deprivation and social discrimination which acquire partial autonomy. The text explicitly concludes that this complexity is borne out by the history of repair, implying that repairing every manifestation of historical injustice is difficult, if not impossible. Option A is incorrect because the text states theorists *must* take it seriously, not that they haven't. Option B is incorrect as it says they resist repair, not that they are *always beyond* repair. Option C is too narrow as the text mentions multiple structural roots, not just bad economies.
