The correct option is B Direct access
Answer: (B) Direct access
A magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data.
Auxiliary storage devices can be categorised as sequential access media and random access media depending on the type of data access.
Sequential access media
Data stored on sequential access media can only be read in the sequence it was stored. To get to a certain point on media, we must first go over all of the preceding points.
Magnetic tape is an instance of sequential access media.
Random access media or Direct access media
Disks, on the other hand, are random-access media (also known as direct access media) since they can access any point at any time without passing through any intervening points.
Some examples of direct access are a magnetic disk, and optical disk.
