Explanation:

Let’s break this down:

- Option 3: Emile Durkheim—He’s the one who developed the concept of anomie. He talked about how rapid social change can leave people feeling disconnected, which can lead to breakdowns in norms and values. That’s anomie.

- Option 1: K. Marx—Marx focused on class conflict and alienation, not anomie.

- Option 2: R.K. Merton—Merton expanded on Durkheim’s idea of anomie, but he didn’t come up with it.

- Option 4: Max Weber—Weber was all about rationalization and bureaucracy, but anomie wasn’t his main thing.

So, Durkheim gets the credit for this one.
