Which question should a buyer ask to check authenticity of an art product?

Correct answer: Which artist or community made it and by what process

A is correct. Asking who made the artwork and how it was made is the most useful way to examine authenticity. It helps verify the product’s traditional source, materials, and technique. A certificate or identification mark may support verification, but by itself it does not fully establish the actual maker and production process. Exam tip: For authenticity checks, mention source, method of making, and supporting documentation.
