b. ". . a non-site city that learned of the project's successes—began developing a similar program of its own based on the preliminary findings from the study."

c. "the nij (national institute of justice)-funded study provides a variety of best practices and may also provide support . ."

d. "half of the cases were randomly selected to be analyzed to see if a dna profile could be determined; the remaining half were not tested . ."

A). "Therefore, arresting burglars using DNA as part of the criminal investigation . . . has the potential to prevent future property and other crimes."

Explanation:

As per the question, option A i.e. 'Therefore, arresting burglars using DNA as part of the criminal investigation . . . has the potential to prevent future property and other crimes' most appropriately represents the author's employment of assumptions as it exemplifies the proposition that is taken to true without examining its validity and presenting without sufficient evidences that justify it. Therefore, this statement reflects that 'the use of DNA as an element of criminal investigation would assist in preventing future property and other crimes' without even testing its truth. Thus, option A is the correct answer.
