No, “set” is correct answer. I think it’s true.

It says env in the text book.
There is a difference between SHELL and ENVIRONMENT variables!
For shell-var´s the correct way is set as right selected in the answer.
For display all environment variables you can use env!

SET is used to get the path value and by experience, ENV is the answer.
