Answer: 3.27 grams
Explanation:
The value that is measured should have minimum error and minimum difference in weight with respect to the actual weight of the equipment.
The original weight of the pellet with a mass of 3.25 grams is measured and the most accurate weight around this number is 3.27.
The slight difference is due to error and this error can be calibrated.
Hence, the correct option is 3.27.
