Criminal Justice - I do not need explanations...Just the letter of the correct answer

In the mid-1990s, the use of DNA fingerprinting emerged and replaced standard fingerprinting evidence in most criminal investigations. DNA fingerprinting is helpful with identification because like fingerprints, no two people (except for identical twins) have the same DNA. DNA evidence has exonerated innocent people who have served many years in jail. It is also, however, seen by many as an invasion of privacy.

In 2013, the U.S. Supreme Court in Maryland v. King reviewed a case where a young man, Mr. King, was arrested, and his DNA was taken and entered into a database. King was implicated in a six-year-old unsolved rape, and found guilty of the crime using the DNA the police took from him when he was in custody for a non-related event. The United States Supreme Court ruled that DNA could be collected, although the decision drew criticism from conservative and liberal justices alike. Considering what you have learned about the DNA investigative revolution in Chapter 5, please answer the following:

Ans 2 : d) DNA databases

The DNA databases of the convicted can be used as an evidence or reliable proof to prove the person guilty.

Ans 3 : c) Tying crimes from different regions to one suspect

CODIS helps to match the profiles of suspects with the biological evidences obtained from the crime locations of different regions.

Ans 4 : c) reliability
