I agree with the above - you really need to indicate what your degree and subsequent masters is, in order to advise you on your best options. Is it research or taught etc.
There really are careers that can get you better paid with a Masters, especially in the current situation where there are so many Bachelors chasing few jobs, and a Masters makes you that bit better. Though it may be that the job only requires you to have a Bachelors in the current times a Masters results in you being paid more since you can get the job ahead of Bachelors.
Unfortunately we are ending up like the US where a Bachelors is something everyone has anyway, and ever more letters after you name are required to differentiate you from the majority.
B or C certainly are the best routes but don't end up flipping burgers - a degree is more valuable and can get you experience that any aviation employer could find useful.
