It's
A drawing question.
In order to answer it you must draw two lines that form the LETTER "A" the third line in the letter "A" will be the great circle track.
Of course you also have to draw the RHUMB line between the two points, this will be an ARC. What you want to do is draw the ARC so that it points towards the EQUATOR.
After you've drawn it you will see that the starting RHUMB LINE track from A is LARGER than the GC track. After this all you have to do is halve the Convergence and SUBTRACT it from the rhumb line TRACK. This will give you your GREAT circle track.
Convergence formula by the way for this> SinLat (mean lat) x Change in longitude= Convergence.
I tried my best here.
