Choosing the option that reflects invalid and potentially misleading data when RADAR is not properly calibrated highlights the critical importance of calibration in ensuring the system's accuracy and reliability. Proper calibration of RADAR systems is essential because it helps align the device's measurements with known standards, enabling it to accurately measure distance, speed, and other parameters.

If a RADAR system is used without calibration, any readings it produces may be incorrect. This can lead to serious consequences, such as misidentifying the speed of moving objects or failing to detect them altogether, which can compromise safety in applications like traffic enforcement or aviation. Misleading data can also affect decision-making processes that rely on accurate information, further underscoring the necessity of regular calibration.

In contrast, the other options suggest outcomes that would not occur if RADAR is improperly calibrated. Accurate speed readings, higher efficiency in operation, and consistent performance over time presuppose that the device has been maintained and calibrated correctly, which is not the case if it is left uncalibrated.
