I've never had my DW on an angle but I would hate it across because water would drip on floor. I like the sink in middle, DW on one side and trash on the other. In option 3 can trash fit on the other side of sink?

For one cook, I like option #2. I'd keep an old kitchen towel under the sink, to toss on the floor when loading the DW.

Can't imagine the DW anywhere but next to the sink.

My kitchen is a small U, with the sink in the middle. The DW is on an adjacent leg, and "dripping water between sink and DW" has never been a problem for us. First, I don't pre-wash my dishes, though some are rinsed in the sink after meals. But it's only a couple of feet - one or two drips, if any, from each dish. My kitchen floor is tile, so a couple of drips won't do it any harm.

That said, in this case I would go with option 3.

Thanks everyone for your opinions, it is a great help to hear everyone's thoughts. My friend and her husband both like different options.

#3 next to the sink. That's the layout I have now. Sink in middle - dishwasher right - trashcan left.

I'll add my qualifying thoughts for choosing #3, which I should have included in my previous hit-and-run post. As AnnKH mentioned, the DW across the aisle is a very short distance, and you probably won't need to reach much further than if the DW was beside the sink. If you like to keep the DW open while you prep, to deposit used utensils and vessels, that location will be convenient. You won't be prepping over a steaming DW, although that one is not a big deal to me. Finally, a feature I love--having the trash pull-out under the prep counter is very convenient--crumbs and debris can be brushed directly into the open can below.

Dish storage might be a little tricky. I'd keep the sink in the same location as plan #1, and store dishes in 24" drawers where the DW is drawn in that plan. Then leave the corner void open, with shelves for glasses or cups. If you wash pots and pans in the DW, unloading them to drawers under the cooktop won't be a problem. Where do you plan to store dishes?

mama goose I'll need to ask her what her plan is for storing the dishes. I'm having trouble convincing her of the whole drawers are better than doors.
