Answer 2

STR, or short tandem repeats. These are short segments (3-5 base pairs) in a genome that are repeated over and over again. If you look at multiple STR regions in two people you can distinguish the people due to the different patterns of their STR regions being analyzed. This needs more than just one STR, the more you look at the worse the odds that any two people would have the same pattern of their STRs.
