A new service tag must be attached each time service is performed. Service tags must be _______ inches in height and _______ inches in width and must not be _______ in color.

• A. 5-1/4 in height; 2-5/8 in width; white
• B. 6 in height; 3 in width; red
• C. 4-1/2 in height; 2 in width; blue
• D. 5 in height; 3 in width; white

Answer: (A)

Service tags need to be clearly legible and easy to identify after each service, so the size and color are specified to ensure readability and visibility. The exact dimensions of 5-1/4 inches in height and 2-5/8 inches in width give enough printable area for the necessary service information while staying compact and fitting into standard tag holders. The color must not be white to avoid low contrast or blending with common backgrounds and lighting, which makes the tag harder to notice at a glance. So this combination of the given height, width, and a non-white color aligns with the standard, while other options deviate in either size or color.
