The correct answer is: B. Message design incorporates audience.
Effective communication takes place when the message is designed in a way that is tailored to the audience. This means taking into account the audience’s needs, interests, and level of knowledge. The message should also be clear, concise, and easy to understand.
The other options are not necessary for effective communication. A source does not need to be attractive or authoritarian in order to communicate effectively. Modern communication technologies can be helpful, but they are not essential. And receivers do not need to be passive recipients in order for communication to be effective. In fact, active participation from the receiver is often necessary for effective communication.
Here is a more detailed explanation of each option:
- Option A: Source is attractive and authoritarian. This option is not necessarily true. While an attractive or authoritarian source may be more likely to be persuasive, this is not always the case. In fact, some people may be more likely to resist messages from sources that they perceive as being too attractive or authoritarian.
- Option B: Message design incorporates audience. This option is the most important factor in effective communication. The message must be designed in a way that is tailored to the audience. This means taking into account the audience’s needs, interests, and level of knowledge. The message should also be clear, concise, and easy to understand.
- Option C: Modern communication technologies are used. This option can be helpful, but it is not essential. Effective communication can take place using a variety of methods, including face-to-face communication, written communication, and electronic communication.
- Option D: Receivers are passive recipient. This option is not necessarily true. In fact, active participation from the receiver is often necessary for effective communication. The receiver must be willing to listen to the message, understand it, and respond to it.
In conclusion, the correct answer is: B. Message design incorporates audience.
