For PJ2
My answer to the quiz was "B" without looking anything up.
For OODA loop:
If your instrument scan has broken down, how are we talking about OODA?
Observe and orient seem to me to require actually seeing something, knowing what it is you are seeing, and using what you know to set up some choices for a decision.
The PF seemed to be going to D without effective OO, hence the A's were not suited to his dogfight, a 1 v 1 with an A330 when he had a wingman there to assist ... too much analogy, sorry.
Cheers.
