B.

C.

The Answer Is:
D
This question includes an explanation.
Explanation:
Direct-attached storage (DAS) is a type of storage that is attached directly to a computer without going through a network.
DAS is typically used for internal storage in personal computers and servers in the form of a hard disk drive (HDD) or solid-state drive (SSD) directly connected to the motherboard.
Direct-attached storage is ephemeral or non-persistent. they persist as long as the instance isn’t deleted; it will not be lost and reset due to reboots.
Direct-attached storage offers limited capacity, but using multiple hard disk drives, we can expand its storage capacity.
