The correct answer is B. DISKCOMP A: B:/l/8.
DISKCOMP is a command-line utility in MS-DOS that compares the contents of two floppy disks. The syntax for the DISKCOMP command is:
DISKCOMP drive1: drive2: [/1] [/8] [/L]
The drive1: and drive2: parameters specify the floppy drives to compare. The /1 parameter specifies that only the first side of each disk should be compared. The /8 parameter specifies that only the first 8 sectors of each track should be compared. The /L parameter specifies that a log file should be created that contains the results of the comparison.
In this case, the command DISKCOMP A: B:/l/8 will compare the contents of the floppy disk in drive A with the floppy disk in drive B, specifying to compare only first side of each disk, and only the first 8 sectors of each track.
The other options are incorrect for the following reasons:
- Option A, DISKCOPY A: B:/8, does not specify that only the first side of each disk should be compared.
- Option C, DISKCOMP A: B:/8, does not specify that only the first 8 sectors of each track should be compared.
- Option D, DISKCOMP A: B:/l, does not specify that the disks should be compared side-by-side.
- Option E, None of the above, is incorrect because the correct answer is B.
