Verbal
Several police departments, including Fort Barnsdale's, have called on Traffnav, a social media navigation company that operates a real-time traffic condition sharing application, to remove the ability to report police officer sightings from the platform. The police departments making the request fear that such information could interfere with law enforcement operations. In response, Traffnav has refused to honor the request, citing that “most users tend to drive more carefully when they believe law enforcement is nearby."

Traffnav's response to the police department's request relies on which of the following assumptions?

Ⓐ Fort Barnsdale has one of the lowest crime rates of any of the cities submitting the request to Traffnav.

Ⓑ Fort Barnsdale does not have the worst traffic conditions of the cities calling the removal of Traffnav’s police location reporting feature.

Ⓒ Fort Barnsdale’s law enforcement officers sometimes use the Traffnav app to avoid traffic congestion or road hazards.

Ⓓ Traffnav's real-time traffic data couldn’t also be used to interfere with law enforcement operations.

Ⓔ Traffnav's real-time traffic data can also be used to avoid law enforcement operations.
