For me:
c) Carry out initial emergency actions (slow to Vse, retard PCL, confirm fire, secure donk, fire #1 bottle) whilst continuing visual approach to land on one engine. At the end of a 100+nm transit, you must be able to achieve that, surely?
Sorry, not an option.
Reason 1, too heavy for a single engine landing. Reason 2, nowhere near enough time to carry out the drill.
