Explanation:

Let’s break it down:

- The statement says property is about rights and duties of one person or group against everyone else, concerning some scarce good—so it’s exclusive, but also social, tied to custom and law.

- This isn’t a definition straight from classical economics. Instead, it’s a sociological take.

Now, about the options:

- Morris Ginsberg: He was known for discussing law, social structure, and sociological ideas, and he actually gave a well-known sociological definition of property much like this one.

- L. Hobhouse: Major sociologist, but focused more on ethics and social evolution, not specifically property in this way.

- Kingsley Davis: Famous in demography and social science, but he’s not known for a property definition along these lines.

- Karl Marx: Analyzed property mainly in economic and class terms, certainly not with this kind of rights/duties wording.

Here’s the thing: Morris Ginsberg is the one who defined property this way.

Correct Answer: Option 1 - Morris Ginsberg
