Answer:

C would be the most effective.

Explanation:

Scratching the minerals with quartz would not be the correct way of finding the hardness, you should scratch the mineral on glass instead. Holding the samples in each hand is ineffective since you would have to assume which has more mass. Dropping the samples would not change anything since they would hit the ground at the same time.
