Sorry EddieHeli, you've applied deviation incorrectly as well. Oxford Blue is right, it's answer (A).
The problem with using + and - for deviation and variation is that it only works mathematically correctly when working in one direction. For instance:
Compass heading 182º, Deviation -2º, Magnetic heading 180º
is correct and makes sense mathematically because 182 - 2 = 180 whereas:
Magnetic heading 180º, Deviation -2º, Compass heading 182º
is also correct but makes no mathematical sense. I would suggest a variation of Notso's idea. Convert the minus sign to 'west' then say:
Deviation West Compass Best
Deviation East Compass Least
Where 'best' means 'a bigger number'. Variation is similar, + is east, - is west as before. The rhyme is as Notso says:
Variation West Magnetic Best
Variation East Magnetic Least
