The correct answer is true.
It is true that Durkheim, Marx, and Weber all examined social change in their work.
These three prominent authors included social change in their many works. When we talk about social change we refer to the way humans interact with each other and how institutions establish relationships to better function in society. As change is the only constant in life, people and institutions have to adapt to the different sets of circumstances at different times. Durkheim, Marx, and Weber studied these cases from their particular points of view.
