Showing error info in PDO:

There are 3 values in the array that is returned by the errorinfo function in PDO.Let see the question now for preparation of ZEND certification test. The bold options are the answers. You can give your opinion about the answers.
Question: Consider the following PHP code segment, which attempts to execute a PDO query:

try {
$dbh->exec($sql);
} catch (PDOException $e) {
// display warning message
$info = $e->errorInfo;
}

In the event of a PDOException, $info is set with the contents of the $errorInfo property of the exception. Which of the following are accurate descriptions of the contents?

a.$info[1] is the database-specific error code
This is right.
b.$info[2] is the database-specific error message
This is right.
c.$info[1] is the unified error code
d.$info[0] is the unified error code
This is right.
e.$info[0] Is the Database-specific error message
