d. both a & b are correct
check answer

Explanation:

In gel - electrophoresis for forensic analysis, if a suspect's DNA banding pattern does not match the crime - scene or victim's pattern, the suspect can be excluded. Here, Suspect 1's bands do not match, so Suspect 1 can be excluded. Suspect 2's bands match, so Suspect 2 cannot be excluded. However, a match only means the suspect cannot be excluded, not that the suspect is guilty as there could be other factors and evidence to consider.

Answer:

d. Both A & B are correct
