White vinegar will inactivate undischarged nematocysts and the toxin so that is my choice.
Do not use fresh water, that will make things worse, not better.
The correct answer is: c - vinegar
The acetic acid in the vinegar deactivates any remaining nematosysts, allowing them to be removed without causing any further discharges into the skin.

Painful memories from Christmas holidays at the beach gives me the answer. Hopefully I was doing the right thing all those years ago.

c. Vinegar
I think that normal saline is OK too. Tap water hurt like buggery and I'd avoid the Windex - it's only for windows or for getting rid of zits...
