Why each option
Data ONTAP Cluster Mode 8.1 supports SMB 1.0, 2.0, and 2.1; SMB 3.0 was not added until a later ONTAP release, and SMB 4.0 does not exist as a protocol standard.
SMB 4.0 does not exist as a defined protocol version in any Microsoft or industry specification.
SMB 3.0 support was not introduced in Cluster-Mode until Data ONTAP 8.2 or later, making it unavailable in the 8.1 release line.
SMB 2.1 is supported starting in Data ONTAP 8.1 Cluster-Mode, providing improvements such as large MTU support and opportunistic locking over the SMB 2.0 dialect.
SMB 2.0 is supported in Data ONTAP 8.1 Cluster-Mode as a significant improvement over the legacy SMB 1.0 dialect, introducing request compounding and larger reads/writes.
SMB 1.0 (the original CIFS dialect) is supported across all ONTAP versions for backward compatibility with legacy Windows and third-party clients.
