The correct answer is: B. two-way process.
Communication is a two-way process because it involves both the sender and the receiver. The sender encodes a message and sends it to the receiver, who decodes the message and responds. This process is repeated until the sender and receiver have reached a mutual understanding.
A one-way process would be if the sender simply sent a message without expecting any response from the receiver. This type of communication is often used in broadcasting, where the sender is trying to reach a large audience with a message. However, it is not effective for building relationships or creating understanding.
A three-way process would be if there were a third party involved in the communication, such as a mediator or interpreter. This type of communication is often used in situations where there is a language barrier or where the sender and receiver have different cultural backgrounds. However, it is not the most common type of communication.
A four-way process would be if there were four people involved in the communication, such as a group discussion. This type of communication is often used in meetings or brainstorming sessions. However, it can be difficult to manage and can lead to confusion if the participants are not careful.
In conclusion, communication is a two-way process that involves both the sender and the receiver. This process is repeated until the sender and receiver have reached a mutual understanding.
