Answer:
D. "Based on information in these databases.....researchers have found that many property offenders do not 'specialize'....."
Step-by-step explanation:
An author must substantiate his central idea through shreds of evidence in order to convey his message effectively. The option that best represents his message is the last option as it illustrates and certifies the author's claim through the information provided by the researchers and databases. The information of databases persuades the readers to believe in the author's message as it is based on factual information and the researcher's remark would affect the opinion and perception of the readers positively which is the ultimate goal of an author.
