How many LEDs are in the Bar Graph Display and what colors are they?

Explanation:
Counting the LEDs and identifying their colors on a Bar Graph Display. In this material, the Bar Graph Display has nine LEDs in total, colored to show different ranges: red indicates a higher or alert level, yellow stands for caution, and green means normal or safe. The exact breakdown is three red LEDs, one yellow LED, and five green LEDs. That combination matches the hardware described for this question, giving a total of nine LEDs with that color mix. Other options would either imply a different total or omit a color that is present on the display, so they don’t align with the actual device used here.
