I like the idea of using an action object as a script (A) - that gives me more control over the data exchange. And the data-pega-event-onpagedata attribute (E) sounds interesting, I'll have to look into that one.
A, B, and D seem like the most straightforward options to exchange data. Using an SQL call to exchange data (C) seems a bit risky and could be overkill for a simple web mashup.
