Final answer:
According to Marx and Engels, the American Revolution would be seen as a class struggle, where the American bourgeoisie was in conflict with the British ruling class.
Step-by-step explanation:
Based on the philosophy of Karl Marx and Friedrich Engels, as expressed in The Communist Manifesto, the authors would view the American Revolution primarily as a class struggle. This perspective is grounded in their belief that all history is characterized by the struggles between opposing classes, in this case, the American colonial bourgeoisie (such as the merchants and property owners) against the British imperial ruling class.
Although the American Revolution had multiple dimensions and causes, including issues such as taxation without representation and the desire for self-governance, from a Marxist perspective, these are seen as manifestations of the underlying class conflicts. Therefore, the answer to the question would be A. It was a class struggle.
