The process which is most likely to be used to determine whether the blood on the glass belongs to the suspect is the second option - STR analysis.
STR stands for Short Tandem Repeat, and refers to comparing DNA from two or more samples.

The process which is most likely to be used by the forensic scientists to match the evidence and suspect blood samples is STR analysis.

STR (Short tandem repeats) analysis is used to analyze individual areas of the DNA (Deoxyribonucleic acid). The STR analysis is performed to compare the two DNA samples. STR analysis is the most recent technique used in the DNA analysis in the field of forensics. The nuclear DNA is extracted from the blood samples and then the selected regions are amplified using the PCR (polymerase chain reaction). The STR sequences are then identified using the gel electrophoresis. These are then compared to find out if the two samples belong to the same person or not

Hence, the answer is 'STR analysis'..
