The following pseudocode is executed using the "Scores" dataset. What does List store at the end of execution? D = { } List = [ ] while (Table 1 has more rows) { Read the first row X from Table 1 if (isKey(D, X.DateOfBirth)) { D[X.DateOfBirth] = D[X.DateOfBirth] ++ [X.SeqNo] } else { D[X.DateOfBirth] = [X.SeqNo] } Move the row X to Table 2 } foreach i in keys(D) { if (length(D[i]) == 1) { List = List ++ D[i] } }

(D) List of sequence number of students who do not share date of birth with another student

(A) Sequence number of students who share date of birth with another student

(B) Sequence number of students who do not share date of birth with another student
