The major difference between the Linear Model of Communication and the Transactional Model of Communication is that O feedback is automatic
O people send and remeive messages at the same time
O noise can interfere with the message
O decoding is learned

B). People send and receive messages at the same time.

Explanation:

The Linear model of communication is a unilateral communication process in which the sender simply transfers the message to the receiver without allowing any interaction to take place. While the Transactional model gives equal significance to both the senders as well as receivers and this is why, it allows interaction to take place and therefore, employed for making Interpersonal communications. The key difference between both models is that the latter(transactional model) allows the sending and receiving of the messages at the same time while the former(linear model) does not. Thus, option B is the correct answer.
