I’d go for E and F.
E because we have few multipass workarea executions which means lack of PGA.
F because of shared servers.

F must be indirectly eliminated as users who complain run DSS queries, those users must use dedicated connections so why to care about large pool for shared servers!

Due to the lack of missing information or insufficient information, I would go with C & E!
