Should I select auto-increment and primary key for the same SQL table column
Question
I am creating a MySQL table with a primary key column; should I also select the auto-increment option or does primary key already do that?

Definitely You should select both. and the reason why you select both is below
Auto-increment allows a unique number to be generated automatically when a new record is inserted into a table.
Often this is the primary key field that we would like to be created automatically every time a new record is inserted.
