Examine this diagram of short tandem repeats found in DNA profiling of three suspects in a crime. Man 1 shares the same number of STRs as 1 in 5,000 people. Man 2 shares the same number of STRs as 1 in 10,000 people. Man 3 shares the same number of STRs as 1 in 3,500 people. DNA extracted from samples at the crime scene found 6 STR repeats, based on the data provided, it can be interpreted that

B. Man 2 must be guilty, based on this proof.
C. no conclusion can be made, because the STRs all repeat the same sequence of C-T-A.
D. Man 2 is likely guilty, considering that he has a rare STR profile that matches crime scene samples.
