The correct answer is Option (1) → Depressed Classes
At the Round Table Conference Mahatma Gandhi stated his arguments against separate electorates for the Depressed Classes:
Separate electorates to the “Untouchables” will ensure them bondage in perpetuity … Do you want the “Untouchables” to remain “Untouchables” for ever? Well, the separate electorates would perpetuate the stigma. What is needed is destruction of “Untouchability”, and when you have done it, the barsinister, which has been imposed by an insolent “superior” class upon an “inferior” class will be destroyed. When you have destroyed the barsinister to whom will you give the separate electorates? |
