Answer:

Option A, Independent testing,repeated in multiple trials

Explanation:

For testing the accuracy of any device, it would be essential to test it randomly on independent observant so that the variability in data set could be captured. Based on this data analysis, corrections in the measuring device must be made. After the corrections, the device must be tested again on the random samples to calculate its accuracy. Independent testing gives unbiased results, while restricted sample testing give biased result.

Hence, option A is correct.
