Facial recognition has presented U$.$S$.$ Customs and Border Protection $($CBP$)$ with the best biometric system because it can be performed relatively quickly, with a high degree of accuracy. The system is also perceived as non$-$invasive to the traveler because no actual physical contact is required to collect the biometric.From the information given above, it CANNOT be validly concluded that

A$)$ given that the biometric system used by CBP is based on facial recognition, the system can be said to be efficient, precise, and non$-$invasive

B$)$ if a biometric system is slow, unreliable; and invasive, then it is not the CBP biometric system based on facial recognition

C$)$ biometric systems that are not based on facial recognition can be non$-$invasive and quick but may lack accuracy

D$)$ whenever the CBP biometric system based on facial recognition is used, it is always fast, accurate, and non$-$invasive

E$)$ at the very least sometimes the biometric system based on facial recognition is fast, accurate, and non$-$invasive
