Explanation:

- Robert Redfield described the "little community" with four main characteristics:

- Distinctiveness: The community is unique and has its own identity.

- Smallness: The community is relatively small in population and area.

- Homogeneity: Members share similar cultural, social, or ethnic backgrounds.

- Self-sufficiency (Option 2) : The community produces most of its needs and is not highly dependent on outsiders.

- Other options:

- Isolation: Refers to being cut off from others, but self-sufficiency better captures Redfield's original idea.

- Interdependence: Suggests reliance on others, which is opposite to self-sufficiency.

- Closure: Means being closed off, but doesn’t specifically mean self-reliant.
