Response choices cover all possibilities so every participant has an option. This describes which property?

• A. Exhaustive
• B. Mutually exclusive
• C. Open-ended questions
• D. Concept

Answer: (A)

Exhaustiveness is the idea that the set of response options covers every possible answer a participant might give. When options are exhaustive, no respondent is left without a suitable category, so each person can be classified into one chosen option. Mutually exclusive would mean the options don’t overlap with each other, which is a different requirement focused on avoiding overlap rather than ensuring all possibilities are represented. Open-ended questions let people provide any answer beyond fixed choices, which is the opposite of having predefined exhaustive options. So the phrase describes exhaustiveness.
