Sort command is basically used for "ordering a file".

- Reverses sort order(-r).
- Sorting on primary key(-k).
- Numeric sort(-n).
- Removing repeated lines(-u).

These are the sorting options.

The sort -r command will first sort then reverse. So, the question is partially wrong. And -k is for sorting with a key reference, not the primary key.

It is sort -r, which sorts the file in reverse order. $man sort for more options and you would get to know the meaning of -r

By default, it orders lines in ASCII collating sequence.
Sort options are:

1. Reverses sort order(-r).
2. Sorting on primary key(-k).
3. Numeric sort(-n).
4. Removing repeated lines(-u).
