Wait, what's a SQL Plan Directive? Is that like a directive from SQL to make our lives more complicated? I'll go with Option E, it's the longest so it must be the right answer.

I think I'll just roll the dice and pick Option B. Capturing SQL plan baselines sounds like it could be relevant, but who knows?

Hmm, I'm not sure. Maybe Option D? Adaptive plans could be related to SQL Plan Directives, right?
