When adding rows to a table, the column names can be omitted if the values are listed in the same order as the columns are listed in the table. This is because the database will automatically match the values to the corresponding columns. Option A is not valid because if there are more than one column, the column names must be explicitly stated after the first column. Option C is not valid because the UPDATE command is used to modify existing records, not add new ones. Option D is incorrect as Option B is a valid statement.
