Why is art useful in explaining difficult subjects?

Because diagrams and pictures clarify concepts

The governing concept is visual communication and the use of art as a learning aid. A diagram can show parts, position, sequence, comparison, or a process in an organised form. Illustrations, maps, models, charts, and labelled drawings make abstract or complicated information more concrete and easier to observe. They also support memory because learners connect words with visible shapes and relationships. Option D is correct because diagrams and pictures clarify concepts rather than merely decorating a page. Options A, B, and C all describe hiding or reducing knowledge, which is opposite to the educational purpose of visual art. Visual material does not replace every explanation, but it can make difficult ideas clearer and more accessible.
