The correct option is "None" because all three statements misrepresent the Congress Socialist Party's ideology. Firstly, while it promoted the idea of boycott as part of broader anti-colonial efforts, it did not primarily focus on the evasion of taxes, which was more associated with radical factions. Secondly, the party did not demand a dictatorship of the proletariat, as it aimed for a democratic socialist framework rather than a Marxist-Leninist revolution. Lastly, it opposed the idea of separate electorates for minorities and oppressed classes, advocating instead for their integration into the mainstream democratic process to foster unity against colonial rule. This context is crucial for understanding the party's objectives and the broader discourse in Indian nationalist movements.
