Which of the following is listed as a specification attribute?

• A. Date/Time format
• B. Font size
• C. Null Handling
• D. Color scheme

Answer: (C)

Null Handling is the specification attribute because it defines how the data element behaves with missing or null values—whether nulls are allowed, what default applies, or how operations should handle them. This is a constraint or rule that governs the data element itself, which is the essence of a specification attribute.

The other options relate to presentation or formatting rather than the data's defined behavior: Date/Time format specifies how values are displayed or parsed, Font size pertains to UI appearance, and Color scheme is about visuals. Those are presentation attributes, not specification attributes.
