Answer: (B)

Saliva is significant in examining bite marks primarily because it can be easily collected through swabbing. When analyzing bite marks, the presence of saliva can provide vital evidence, as it may contain biological material that is useful for DNA analysis. The consistency and composition of saliva allow forensic investigators to obtain samples from the bite area efficiently, enhancing the likelihood of gathering conclusive evidence regarding the individual who left the bite mark. Additionally, the ability to swab saliva means that it can capture any DNA present, thus linking a suspect to the bite mark through genetic analysis. This aspect makes saliva an essential element in forensic examinations, often leading to further investigative leads and conclusions regarding the incident in question.
