Answer: B

Explanation:

The seq command in Linux is used to generate a sequence of numbers from FIRST to LAST in steps of

INCREMENT1. The syntax for the seq command is:

seq [OPTION]… LAST or seq [OPTION]… FIRST LAST or seq [OPTION]… FIRST INCREMENT LAST

In this case, the command seq 1 5 20 has three arguments: FIRST = 1, INCREMENT = 5, and LAST = 20.

This means that the command will produce numbers from 1 to 20 in steps of 5. The output will be:

151015

The output will not include 20 because it is not a multiple of 5. The output will be printed on separate lines by default, unless a different separator is specified with the -s option2.
