Which color indicates 35 and above and requires immediate element change?

• A. Green
• B. Yellow
• C. Blue
• D. Red

Answer: (D)

Red is used to signal the highest level of urgency. When the indicator shows 35 and above, the red color tells you the situation is out of safe range and requires immediate element change to prevent damage or failure. Green normally means everything is OK, yellow signals caution and a potential issue to monitor, and blue often conveys information or a lower-priority condition. So the combination of a high value (35+) with red makes it clear that immediate action is required, which is why red is the best choice here.
