"The Communist Manifesto" is a political document written by Karl Marx along with Friedrich Engels, hence option 2 is the correct answer. Here`s some clarification on the other options.

Option 1, Emile Durkheim, was a French sociologist, but he was not involved in writing "The Communist Manifesto." He is known for establishing sociology as a discipline and his influence on social theory.

Option 3, Robert Owen, was a Welsh textile manufacturer turned social reformer, and a major influence in early socialism. However, he didn`t co-author the Communist Manifesto.

Option 4, Max Weber, was a German sociologist, jurist, and political economist who is best known for his work on the theory of social action, but did not collaborate with Marx on the Manifesto.

So, the correct answer remains Friedrich Engels, who along with Karl Marx wrote "The Communist Manifesto" in 1848, a cornerstone document of Marxist thought.
