IMO B.. all the other angles can be used to return to other terminals..

It quite simple when you realize that all you are doing is finding all the angles in the shape.

It give you 135 and 120.

So two angles of the large triangle are 60 and 45.

From there on you can find all the angles.

Furthermore, do not consider turning onto the terminal as an option to getting to a different runway.
