Explanation:

- Correct Answer: Option 4 - three sides

- A peninsula is a landform that extends out into a body of water and is surrounded by water on three sides.

- The term comes from the Latin "paeninsula," where "paene" means almost and "insula" means island, indicating it's almost an island because it's nearly encircled by water.

- Option 1: one side

- If land is surrounded by water on one side, it is typically just a shoreline or coast.

- Option 2: four sides

- A landform surrounded by water on four sides is generally an island, not a peninsula.

- Option 3: two sides

- A land not forming a peninsula but possibly a strait or similar, narrower shape could be bordered by water on two major sides.

- Peninsulas are prominent geographic features and examples include the Florida Peninsula, the Iberian Peninsula, and the Italian Peninsula.
