01 Why is art called a medium of human expression?
Answer and explanation
Correct answer: A. Because it expresses feelings and ideas.
Explanation: The governing concept is art as a medium of human expression. A medium is a means through which a person communicates something; in art, that communication may use line, colour, shape, sound, movement, language, material, space, or performance. Artists can express emotions, ideas, memories, observations, beliefs, and social concerns even when they do not state them in ordinary sentences. Option A is correct because it identifies the two central contents communicated through art: feelings and ideas. Art may sometimes conceal an object, include mathematics, or involve play, but those are occasional features or uses, not its defining purpose. Thus B, C, and D are incorrect.
