Which statement best defines a peninsula?

• A. A large island fully surrounded by water
• B. A landmass projecting into water and connected to the mainland
• C. A narrow channel of water between two lands
• D. A broad area of flat land

Answer: (B)

A peninsula is a landmass that sticks out into a body of water while still being connected to the mainland. That connection is what sets it apart from an island, which is completely surrounded by water. The key feature is the projection into the water with a remaining link to the larger landmass, which is why the description of a landmass projecting into water and connected to the mainland is the best fit. The other options describe different forms: an island would be entirely surrounded by water; a narrow channel of water between lands is a channel or strait, not a landform like a peninsula; a broad area of flat land describes a plain, not a water- and land-connected projection.
