Step 1: Analyzing the clues.
The clues are: Narrow, River, Water, and Sea. Let’s look for a word that fits all the clues.
Step 2: Exploring the alternatives.
(A) Creek: A "Creek" is a narrow body of water, related to "River" (as a creek is a small river), "Water" (creeks contain water), and "Sea" (creeks can feed into the sea). This fits all the clues.
(B) Ocean: The "Ocean" is vast, but it doesn’t fit with "Narrow" or "River."
(C) Vast: "Vast" doesn’t connect well with "Narrow," "River," or "Sea."
(D) Green: "Green" doesn’t fit with the clues.
(E) Fish: "Fish" doesn’t connect with "Narrow" or "River."
Step 3: Conclusion.
The correct answer is (A) Creek, as it connects to all the clues in different ways.
