Giving importance to workers' committees in factories strengthened which claim of Bolshevik politics?

Correct answer: Workers' participation in power

The governing concept is workers’ control and the socialist claim that political power should reflect the interests of labouring people. Factory committees gave workers an organised role in supervising production, discussing workplace conditions and influencing decisions during the revolutionary period. Their importance therefore supported the Bolshevik promise that workers, rather than the Tsar, factory owners or other privileged groups, would participate in governing society. Option D is correct because it connects the institution directly with workers’ participation in power. Option A is contradicted by the committees’ revolutionary purpose. Options B and C concern the Church and trade, neither of which explains why factory-based worker organisations were politically important.
