How did the influence of the Russian Revolution reach the working class?

Correct answer: Through organisations, parties and spread of ideas

The influence of the Russian Revolution reached workers through political organisations, communist and socialist parties, trade-union networks, newspapers, meetings and the circulation of revolutionary ideas. These channels translated events in Russia into programmes and debates relevant to workers in other countries. Option A is correct because it identifies both organised political activity and the spread of ideas. Options B, C and D are unsuitable: royal courts and feudal tax records were not the principal means of mobilising workers, and Church sermons alone cannot explain the international growth of socialist politics. The influence travelled through people and institutions that discussed class, exploitation, equality and workers’ rights, allowing local movements to connect with a wider international current.
