Which of the following expansion cards should be installed in a server to allow the server to connect to a SAN via a fiber channel?

SATA (Serial Advanced Technology Attachment) is an interface primarily used for connecting storage devices directly within a server, not for connecting to a Fibre Channel SAN.

iSCSI (internet Small Computer System Interface) is a protocol that allows SCSI commands to be sent over IP networks, connecting to a SAN via standard Ethernet, not Fibre Channel.

SCSI (Small Computer System Interface) is a standard for connecting and transferring data with peripheral devices, but it refers to the protocol, not the physical adapter card for Fibre Channel SAN connectivity.

An HBA (Host Bus Adapter) is an expansion card that provides connectivity between a host server and a storage area network (SAN). For Fibre Channel SANs, a Fibre Channel HBA is specifically used to translate data between the server's internal bus and the Fibre Channel protocol for high-speed storage access.
