b) The cost difference between the actual amount of production materials used and those expected to be used (using the actual price).

c) Neither of the above, it is not the cost difference, but simply the difference in quantity actually used and the expected quantity used for production. Cost has nothing to do with the variance calculations.

d) All of the above.
