Which destination should you use?

You are developing a SQL Server Integration Services (SSIS) package to load data into a
SQL Server table on ServerA, The package includes a data flow and is executed on
ServerB, The destination table has its own identity column.
The destination data load has the following requirements:
The identity values from the source table must be used.

Default constraints on the destination table must be ignored.
Batch size must be 100,000 rows.
You need to add a destination and configure it to meet the requirements.

I’m surprised there isn’t more discussion on this. Is the answer so obvious?
https://datatellblog.wordpress.com/2015/01/13/ssis-data-flows-ado-net-vs-ole-db-vs-odbc/

ADO is slower than ole db. Sql Server is only good locally. Both ADO and ole db allows for 100,000 row batches

oledb allows destinations to have their own identities and ignore constraints

As far as I can tell ADO doesn’t explicitly have these options, but so what? Does it always choke on the constraints? A is probably best
