Here is the clue guys......."BRONZE BADGE"...... meaning, I just
learned how to fly a glider and Im trying to get to the destination
airport.

Lets start with best L/D because Im trying to not land out and time is
not an issue, and then add 1/2 the windspeed, since most gliders will
do this and still be on a reasonably decent part of the polar in terms
of sink...and get some better penetration.

I say "A" is the correct answer for a Bronze Badge level pilot since
they base their knowledge on a lot of generalizations about performance
to make inflight calculations relatively easy...

...of course the contest level pilot will have a much more refined
answer with his vast knowledge of his own glider and intimacy with its
performance specs, along with his computer instruments that he can
program for optimum results.
