Explanation:
The queries that will return all the rows from the COLORS table are those that ensure every record from COLORS is selected, regardless of whether there's a matching record in the BRICKS table:
Option A:
Option B:
Options C, D, and E will not return all the rows from the COLORS table:
Option C: The full join will return all rows from both tables, but it is not restricted to only the rows from COLORS.
Option D: An inner join will return only the matching rows between both tables, not all rows from COLORS.
Option E: This is a left join, which would typically return all rows from COLORS, but the WHERE clause restricts the result set to only those rows from COLORS that have a matching BRICK_ID in BRICKS which is greater than 0, potentially excluding rows from COLORS.
