To answer this question, we need to understand the given SQL query and how it filters and sorts the data.
The SQL query is as follows:
SELECT * FROM seating WHERE seat_2 = 'boy' ORDER BY seat_3 DESC, seat_1
This query selects all rows from the "seating" table where the value in the "seat_2" column is 'boy'. It then orders the results by the "seat_3" column in descending order, and if there are any ties, it further orders by the "seat_1" column.
Let's go through each option to determine which row is first in the results set.
Option A) Row 2 - This option is incorrect because the value in the "seat_2" column for row 2 is 'girl', not 'boy'.
Option B) Row 4 - This option is incorrect because the value in the "seat_2" column for row 4 is 'boy', but the value in the "seat_3" column for row 4 is 'girl'. Since the query orders by "seat_3" in descending order, this row will not be first in the results set.
Option C) Row 5 - This option is correct because the value in the "seat_2" column for row 5 is 'boy', and the value in the "seat_3" column for row 5 is 'girl'. Since the query orders by "seat_3" in descending order, and there are no other rows with a higher value in "seat_3", row 5 will be the first row in the results set.
Option D) Row 6 - This option is incorrect because the value in the "seat_2" column for row 6 is 'boy', but the value in the "seat_3" column for row 6 is 'boy'. Since the query orders by "seat_3" in descending order, this row will not be first in the results set.
Therefore, the correct answer is option C. Row 5 is the first row in the results set returned by the SQL statement.
