select the correct answer. which telecommunications device is widely used in industries that require closed communication? a. fixed - line telephones b. mobile phones c. satphones d. walkie - talkies e. small phones

Answer

Answer:

D. walkie - talkies

Brief Explanations:

Walkie - talkies are used for closed - circuit communication in industries as they allow direct and private communication within a limited range. Fixed - line phones are not as mobile, mobile phones and satphones are more for open - network communication, and "small phones" is a non - specific term.
