which of the forms of socialism might Marx himself have been the most/least sympathetic and would any appeal in the US

original question: With which of the variant forms of socialism might Marx himself have been the most and least sympathetic? Which of them do you think would have had the most appeal in the United States? How might a manager or owner of an industrial enterprise respond to these ideas?

this question is in regards to socialism during the revolutions of industrialization. And i know that this question is actually 3 in one, but in my assignment it is to be answered as a whole. It only needs to be at least a paragraph long with an introduction and conclusion sentence.
