Explanation

Input validation controls verify that data entered into a system conforms to expected formats, lengths, and patterns at the point of entry. For credit card numbers, this includes checks such as the Luhn algorithm, correct digit count, and valid issuer prefixes - ensuring the number is structurally correct before it is stored or processed. Input reference controls (A) verify against reference data rather than format. Access controls (B) restrict who can view or modify data but do not ensure accuracy. Reconciliation controls (D) detect discrepancies after the fact rather than preventing inaccurate input.
