Answer: (D)

A 21 gauge needle is represented by the color green. This color coding system is essential for phlebotomy technicians as it helps identify the size of the needle without the need to read the gauge number. In the standard color code for needles, different colors correspond to different gauges, with green specifically indicating a 21 gauge, which is a popular choice for various blood collection and intravenous procedures due to its balance between flow rate and patient comfort. The color coding facilitates quick identification in clinical settings, ensuring efficient and accurate procedures. Understanding the color coding is critical for phlebotomy technicians to select the appropriate needle size for their tasks.
