Which color is one of the five color bands used on the bottle?

• A. Purple
• B. Blue
• C. Teal
• D. Silver

Answer: (B)

Color coding on a bottle uses a set of distinct bands so anyone can identify the bottle’s category or contents at a glance, even in stressful conditions. In the standard five-band scheme used in this context, blue is included as one of the colors because it provides clear contrast and a specific, designated meaning within that system. This makes it easy to spot quickly and reduces the chance of misidentifying the bottle. The other colors listed aren’t part of this particular five-band set, which is why blue is the correct choice here.
