Any numerical field in the business model is always a measure, and a measure is always a numerical field.
B
Correct answer
Explanation
This is false. While measures are typically numeric, not all numerical fields are measures. A measure must be aggregatable and meaningful for analysis - e.g., a numeric ID or phone number is numeric but is a dimension attribute, not a measure. Conversely, all measures in a properly designed business model are numeric (since they represent quantifiable metrics), but the reverse isn't true. The statement creates an incorrect bidirectional implication.
