Answer 1

None of the given answers are correct, as they return an disassociated set of data that does not represent one exact column. The id may not be the id from the same row as the onsale value.

The following will work:

SELECT
    id, onsale, magazine
FROM (
    SELECT
       id, onsale, magazine
    FROM
        product
    ORDER BY
        onsale DESC) AS a
GROUP BY
    magazine
