Select the option that best explains the information conveyed in the sentence.The investigators stated clearly that they had reached a dead end in their scrutiny of suspects in the murder case?

Answer Details

The sentence "The investigators stated clearly that they had reached a dead end in their scrutiny of suspects in the murder case" means that the investigators have thoroughly examined all the suspects in the murder case, but have not been able to find any conclusive evidence to solve the case. Therefore, they cannot proceed further with their investigation at the moment. This is best explained by the option "There was no further progress in the investigation of the murder suspects."
