Question

an archipelago is a group of islands close together in a large body of water. select the archipelago.

Explanation:

To identify the archipelago, we use the definition: a group of islands close together in a large body of water. The first image shows multiple islands (landmasses) close together in blue water (large body of water). The second image appears to be a coastal area with a single landmass and a body of water, not multiple islands. The third image shows a river delta, not islands. So the first image is the archipelago.

Answer:

The first image (the left - most one with multiple landmasses/islands in a large body of blue water) is the archipelago.
