A. Internal Interference.
Interference can be explained as anything that comes between a communication process. This is further explained as a barrier that serves as a distraction in the process of communication. And it can either be Internal or External.
It is internal when the source is from within an individual, and it is external when what causes it (its source) is from the external environment.
Examples of Internal Interference are fear, anxiety, headache, etc.
Examples of External Interference include loud music in an examination hall, honking while speaking over the phone, etc.
In Jeron's case, the distraction is his headache, which is from within him. Hence, the Internal Interference caused the communication to be a failure.
Feedback and Ethnocentrisme channel talks about other things out of the scope of the question.
