B is correct
SAS (Serial Attached SCSI) is an interface type that supports high-speed data transfer and high-performance hard drives, such as 15,000rpm drives. SAS drives are commonly used in servers that require fast access and reliability. IDE (Integrated Drive Electronics), eSATA (external SATA), and SATA (Serial ATA) are not suitable for 15,000rpm drives, as they have lower speed and performance.

SAS (Serial Attached SCSI): SAS is designed for high-performance enterprise storage solutions, including servers and data centers. It supports high-speed data transfers and is commonly used for high-RPM hard drives like those running at 15,000 RPM. SAS drives offer better performance and reliability compared to other interfaces.
The 15,000rpm hard drives used in servers are typically connected using the SAS (Serial Attached SCSI) interface. SAS provides higher performance and reliability compared to SATA (Serial ATA) and is commonly used in enterprise-level servers where fast and reliable data access is crucial.
B. SAS (Serial Attached SCSI)
Most HDDs use a SATA interface, though you may come across legacy devices using EIDE/PATA or SCSI interfaces.
But the question asking what is most likely used. Since its 2024, SATA are the modern cables for hard drives.
