If a person reads a message but does not perform the expected action what aspect of communication should be checked?

Correct answer: Whether the instructions were clear, complete and actionable

The governing concept is effective communication and feedback toward a desired outcome. Reading or receiving a message does not prove that the receiver understood what to do. The sender should check whether the instruction states the required action, includes necessary details and is feasible for the receiver. Option A is correct for this reason. Colour, decorative font and the sender’s smile may affect presentation in some contexts, but they do not establish whether the instruction was actionable.
