A fingermark is to be matched against possible candidate fingerprints on file, using a minutiae-based matching method. Assume, for simplicity, 10 minutiae are compared between the images. After the images are translated and superimposed, the 10 minutiae pairs are identified and their differences are evaluated. The following table shows the differences of the minutiae pairs when compared against each of eight candidates.
Assume the threshold is set to 80%, which means that the two fingerprints will be considered as a match only if the differences of at least 8 out of the 10 pairs are at or below the acceptable difference. Also assume the acceptable difference 0.05 or less.
Which of the eight candidates will be considered a match? Select at least 1 answer.
