Correct answer: (A) Source, message, interference, channel, receiver, feedback and context

Explanation

The essential components of communication are source, message, interference, channel, receiver, feedback and context.

The source encodes a message, sends it through a channel, and the receiver decodes it and returns feedback within a context.

The list built around sign, destination, interaction and correlation mixes in terms that are not the core components.

The set naming signs, symbols, understanding and communicant repeats vague ideas and omits channel and feedback.

The grouping of purpose, ideas, opinions and reaction lists effects rather than the structural elements.

Interference, better known as noise, is any disturbance that distorts the message in transit.
