You need to ensure that auditing is configured to meet these requirements

You are developing a SQL Server Integration Services (SSIS) package to load data into a
Windows Azure SQL Database database. The package consists of several data flow tasks.
The package has the following auditing requirements:
If a data flow task fails, a Transact-SQL (T-SQL) script must be executed.
The T-SQL script must be executed only once per data flow task that fails, regardless of the
nature of the error.
You need to ensure that auditing is configured to meet these requirements.
What should you do?

A.
Use an event handler for OnError for the package.

B.
Use an event handler for OnError for each data flow task.

C.
Use an event handler for OnTaskFailed for the package.

D.
View the job history for the SQL Server Agent job.

E.
View the All Messages subsection of the All Executions report for the package.

F.
Store the System::SourceID variable in the custom log table.

G.
Store the System::ServerExecutionID variable in the custom log table.

H.
Store the System::ExecutionInstanceGUID variable in the custom log table.

I.
Enable the SSIS log provider for SQL Server for OnError in the package control flow.

J.
Enable the SSIS log provider for SQL Server for OnTaskFailed in the package control
flow.
K.
Deploy the project by using dtutil.exe with the /COPY DTS option.
L.
Deploy the project by using dtutil.exe with the /COPY SQL option.
M.
Deploy the .ispac file by using the Integration Services Deployment Wizard.
N.
Create a SQL Server Agent job to execute the SSISDB.catalog.va!idate_project stored
procedure.
O.
Create a SQL Server Agent job to execute the SSISDB.catalog.validate_package stored
procedure.
P.
Create a SQL Server Agent job to execute the
SSISDB.catalog.create_execution and SSISDB.catalog.start_execution stored procedures.
R.
Create a table to store error information. Create an error output on each data flow
destination that writes OnTaskFailed event text to the table.
