Which of the following analogies best represents the relationship between "Ocean" and "Water"?

Ocean : Water -> “a larger whole made up of many units of the second thing.”

• Mountain : Valley → A mountain is not made up of valleys. They are different landforms.
• Forest : Trees → Correct. A forest consists of many trees, just as an ocean consists of water.
• Sky : Cloud → The sky contains clouds, but it is not made up of clouds.
• River : Stream → A river may be fed by streams, but a river is not simply made up of streams.
