In the model of customer-initiated interactive communication, the relevant choices could include:
- The receiver
- The source message
- A message channel
The other options, "Additional noise," "Constant pushing," and "A search," may not specifically fit into the standard model components of customer-initiated interactive communication. However, "Additional noise" could be relevant in a broader context of communication as it refers to any interference affecting the message being conveyed but isn’t a specific component of the model.
Therefore, the most accurate selections are:
- The receiver
- The source message
- A message channel
