A Correct answer
Explanation

The first 6 digits of a credit card number constitute the Issuer Identification Number (IIN), formerly called Bank Identification Number (BIN). These digits identify the card network (Visa, Mastercard, etc.) and the issuing bank. The Major Industry Identifier (MII) is actually just the first digit, not the first six. The account number and checksum follow the IIN.
