How many bars does the sensor radar have?

• A. 2
• B. 3
• C. 5
• D. 4

Answer: (D)

The sensor radar uses a four-bar display. Each bar represents a discrete level of detection strength or a range segment, and the total number is fixed at four in this device. This makes it quick to read: more bars mean stronger signal or greater range within the sensor’s design, up to the maximum when all four are lit. Fewer bars would understate what the display can show, and more bars would go beyond how this radar is built, so four is the correct representation.
