The correct answer is: A. Linux
Linux uses the Linux partition table format, also known as the MBR (Master Boot Record) partition table format. This format is used by most Linux distributions, as well as some other operating systems such as FreeBSD and OpenBSD.
The MBR partition table format is a 512-byte table that stores information about the partitions on a disk. It can store up to four primary partitions or three primary partitions and one extended partition. The extended partition can then be subdivided into logical partitions.
The MBR partition table format is a relatively old format, and it has some limitations. For example, it can only store up to 2TB of data. However, it is still a widely used format, and it is supported by most operating systems.
The other options are incorrect because they are not partition table formats that are used by Linux.
- Option B, BSD, is a family of Unix-like operating systems. It does not have a specific partition table format.
- Option C, UnixWare, is a discontinued Unix operating system. It used the UFS (Unix File System) partition table format.
- Option D, DOS, is a discontinued operating system. It used the FAT (File Allocation Table) partition table format.
- Option E, None of the above, is incorrect because Linux does use a partition table format.
