Answer 1

The correct option for a properly structured SQL transaction is option c, which starts with a 'Begin' statement, ends with a 'Commit' statement, and separates each SQL statement with a semicolon.

Correct option is A

Step-by-step explanation:

The question refers to the structure of SQL transactions. The correct statement for a structured transaction is option c. In SQL, each statement within a transaction should be ended with a semicolon, and the transaction itself should start with a Begin (or Begin Transaction) statement and end with a Commit statement. The format usually looks like this:

Begin;
insert into table_name (column1, column2) values (value1, value2);
...
Commit;

Begin insert into album (album id, title, artist id) values (400, 'new album', 5);
insert into playlist (playlist id, name) values (40, 'top 40'), (41, 'top 40'), (42, 'top 40');
insert into album (artist id, title, album id) values (1, 'my album', 348);
Commit;

Each statement is separated by a semicolon, and the transaction is correctly begun and committed.
