Which is a correct example of product diversification in traditional visual art occupation?

Correct answer: Applying painting style on cards and home decor

The direct answer is A: applying a painting style on cards and home decor. Product diversification means using an existing artistic skill or design to create different kinds of products for different uses and customers. Step by step: the artist begins with a traditional painting style; instead of using it on only one type of artwork, the artist applies it to greeting cards, decorative objects, wall items, or home accessories; these additional products can reach new buyers and create more sources of income. Option A is correct because it combines tradition with new product forms. Option B, keeping art only inside museums, may preserve or display art but does not diversify products or expand ordinary sales. Option C, giving no work to artists, cannot create products or livelihoods. Option D, erasing all designs, destroys the artistic resource rather than developing it. Diversification does not require abandoning tradition; it means adapting the style carefully while respecting its identity. Memory cue: one art style, many useful products means product diversification.
