Final answer:
Version 1 QR Code, the smallest available size with a 21x21 matrix, has no Alignment Patterns. Alignment Patterns help align QR Codes, but they're not necessary for the smallest size.
Step-by-step explanation:
Version 1 QR Code has no Alignment Patterns. Alignment Patterns are part of the structure in QR Codes used to align the code properly to ensure it can be read correctly no matter the angle from which it is scanned. These patterns become necessary as the size of the QR Code increases with more data. However, in a Version 1 QR Code, which is the smallest available size, consisting of a 21x21 matrix, there are no Alignment Patterns required because of its small size. Instead, only the finder patterns and timing patterns which are present in all QR Code versions are used to correctly align and read the QR Code.
