Which objective requirement example specifies a color constraint?

Which objective requirement example specifies a color constraint?

• A. Must seat 6 people
• B. Must have a towing capacity of 4 tons
• C. Must have a fuel economy of 30+ mpg
• D. Must be grey or gold

Answer: (D)

The concept here is distinguishing a requirement that governs appearance, specifically color, from other kinds of constraints. A color constraint is an objective requirement because it can be verified by simply observing the item’s color and checking it against the allowed options. The option that says it must be grey or gold directly imposes a color choice, restricting how the item must look. The other statements specify quantity or performance characteristics—seating capacity, towing capacity, and fuel economy—which are functional criteria, not about color. So the color-constrained option is the one that limits appearance by color.
