Step 1: Analyzing the clues.
The clues are: Stool, Water, Drip, and Dribble. We need to find a word that connects to all of these.
Step 2: Exploring the alternatives.
(A) Drool: "Drool" could relate to "Drip" but doesn’t fit well with the other clues.
(B) Ball: "Ball" fits with "Dribble" (to dribble a ball), "Water" (a water ball), and "Stool" (a ball can be placed on a stool). This fits all the clues.
(C) Patient: "Patient" doesn’t connect to "Dribble," "Drip," or "Stool."
(D) Blue: "Blue" doesn’t fit with any of the clues.
(E) Test: "Test" doesn’t fit with the clues either.
Step 3: Conclusion.
The correct answer is (B) Ball, as it connects to all the clues in different contexts.
