In a Situation Where Police Investigators Want to Obtain Historical

In a situation where police investigators want to obtain historical cell phone location data from a potential defendant's cell phone usage:

A) a potential defendant has no expectation of privacy of data that he or she has voluntarily conveyed to a third-party cell phone carrier.
B) the suspect has no expectation of privacy of cell phone records because everyone knows that such data is not considered private by society.
C) no warrant is required, and the evidence is admissible because in using a cell phone, a suspect or a defendant consents to such information generated by the phone as being available to law enforcement officials.
D) a warrant is required to obtain historical cell phone location data if the cell phone location data evidence is expected to be introduced against a suspect or defendant at a trial.
