If the magnetic heading is greater than the compass heading，the deviation is（）.

A.The readings are too low (small numerically) and the amount of the error must be added to the compass to obtain true
B.The readings are too low and the amount of the error must be subtracted from the compass to obtain true
C.The readings are too high (large numerically) and the amount of the error must be added to the compass to obtain true
D.The readings are too high and the amount of the error must be subtracted from the compass to obtain true

A.the deviation has been offset by the variation
B.there is something wrong with the compass
C.the compass is being influenced by nearby metals
D.there is no deviation on that heading

A.Compass error and variation are equal
B.Compass north will be true north
C.Variation will equal deviation
D.There will be no compass error
