Which principle is correct when communicating the same message to different age groups?

Correct answer: Language and examples should be adapted to the audience level

The governing concept is audience-centred communication. Age, prior knowledge, vocabulary, and experience influence how a receiver understands a message, so the communicator should adjust language, examples, and sometimes the presentation method. Option A expresses this principle. Using the same difficult language may exclude learners, changing colour alone does not ensure understanding, and avoiding feedback prevents useful checking.
