C. Compare recoverable DNA from the lock of hair to a Sibling of the Victim's DNA
D. You cannot recover DNA unless you have a follicle, and since the hair was cut, you cannot be certain.

Answer 1

D. You cannot recover DNA unless you have a follicle, and since the hair was cut, you cannot be certain.

Step-by-step explanation:

The hair follicle at the base of human hairs contains cellular material rich in DNA. In order to be used for DNA analysis, the hair must have been pulled from the body. Hairs that have been broken off [or in this case, cut] do not contain DNA.

Hope this helps :)
