The following passage is from The Communist Manifesto written by Karl Marx in 1848.“Let the ruling classes tremble at a Communist revolution. The proletarians [workers] have nothing to lose but their chains. They have a world to win. Working men of all countries, unite!”

Marx calls on workers in every country to “unite” and describes them as having a world to win through revolution. This supports the idea that workers should join together in the communist movement. Choice B is the best match; the passage does not specifically tell workers to scare rulers into surrendering their wealth.
