According to the transactional model of communication the sender must be _________ and ________ before he/she wants to send a message.​

A) Stimulated/motivated
B) Stimulated/encouraged
C) Encouraged/listened to
D) ​Received/motivated

According to the transactional model of communication, communication is a two-way process, and the sender must have the desire or motivation to communicate a message. The sender must also be stimulated or influenced by some internal or external factor to initiate the communication process. Therefore, option A is the correct answer. Option B talks about encouragement, which is more about receiving communication from others, so it is not applicable here. Option C talks about listening, which is more about being a receiver, so it is also not relevant here. Option D talks about receiving, which is one aspect of communication, but it does not cover the sender's motivation to send the message.
