Correct answer: (B) A variable — A characteristic that can take different values or categories is a variable, so that is the answer.
Explanation
★A characteristic that can take different values or categories is a variable, so that is the answer.
★A variable is anything that varies, taking different values or categories across cases.
★So a condition that can change from one value or category to another is a variable.
★A constant, by contrast, always stays the same and does not vary.
★A cause-and-effect relationship is a link between variables, not a single characteristic.
★A descriptive relationship is again a relation, so a varying characteristic is a variable.
