Explanation

A fingerprint reader is most secure because it relies on biometric authentication - something you physically are - which cannot be lost, stolen, duplicated, or shared as easily as physical or knowledge-based credentials.

A (Coded lock): A combination/PIN can be observed (shoulder surfing), shared, or guessed through repeated attempts.
B (Ordinary key): A physical key can be copied, lost, or stolen with minimal effort.
D (Contactless smart card): Cards can be cloned using RFID skimmers, lost, or stolen - possession alone grants access with no identity verification.

Memory tip: Think "what you are > what you have > what you know" - biometrics (fingerprint) sit at the top of this security hierarchy because they're inherently tied to the individual and can't simply change hands.
