Here are two relations, R(A,B), S(C,D). (see figure): **Table R:** | A | B | |---|---| | 1 | 4 | | 2 | 5 | | 3 | 6 | | 4 | 7 | **Table S:** | C | D | |---|---| | 0 | 1 | | 1 | 0 | | 2 | 1 | Compute the result of the query: ```sql SELECT A, B, C, D FROM R LEFT OUTER JOIN S ON R.A = S.C ``` Identify, in the list below, the row that appears in the result.
