Explanation:

• Operational definitions must be clear, not vague, so the first option is false.
• Studies often use multiple operational definitions for different concepts, so the second option is false.
• Operational definitions translate abstract concepts into measurable, concrete terms, acting as a clear explanation of abstract ideas, making the third option true.
• The goal of research is to test hypotheses related to concepts (not falsify operational definitions themselves), so the fourth option is false.

Answer:

An operational definition serves as a useful explanation of an abstract concept.
