Final answer:
option c,A Mobile radio has an output of 20 to 50 watts and a range of 10 to 15 miles, fitting the description of the communication device mentioned.
Step-by-step explanation:
The communication device that has an output of 20 to 50 watts and a range of 10 to 15 miles is most likely a Mobile radio. Base stations typically have higher outputs and ranges, while portable radios usually have lower outputs and ranges. Repeaters, on the other hand, are not a direct source of transmission but rather devices that extend the range of communications by receiving and retransmitting signals. Mobile radios are designed for use in vehicles and can operate within the given power and range specifications. They serve as an essential part of communication for professionals who need reliable communication over moderate distances, such as first responders and truck fleets.
The communication device with an output of 20 to 50 watts and a range of 10 to 15 miles is a Mobile radio. Mobile radios are commonly used in vehicles for communication purposes. They have a higher power output and range compared to portable radios, base stations, and repeaters.
