A standard for each loop container cannot process items in parallel! In a sequentiell container you can process tasks in parallel.

Thanks, you are right. Sequence container can do tasks within in sequence (when connected) or in parallel (when not connected).

Parallel Loop Task is not native SSIS task. So G

So the answer is H "Foreach loop Container" ?

I think the right answer is Sequential container. A standard foreach loop cannot process items in parallel. With a sequence container any tasks that are not preceded by a precedence constraint will run in parallel.

Sure? The answer talks about parallel loop container which is not standard in SSIS (see Reference). Although, putting all 24 data flows in one for each loop container should do the work.
