a.) only one of the suspects can be ruled out
b.)non of the suspects can be ruled out.
c.) all of the suspects can be ruled out
d.) a mistake must have been made and the test will have to be run again.

Answer 1

All of the suspects can be ruled out would be my guess :/

Answer 2

Answer:all of the suspects can be ruled out.

Explanation:

All of the suspects can be ruled out because the DNA results must match with one of the suspects before he/she can be considered to be the murderer. The DNA of an individual which is his/her genetic make up is his/her identity and is unique to each individual.

So the DNA samples obtained from the victim must match exactly with someone before the person can be accurately accused as the murderer.
