Final answer:

Step-by-step explanation:
The question is asking about the analysis of Marcel Duchamp's artwork Bicycle Wheel, specifically focusing on the sign of the artist's hand, authenticity, value, and subject matter. In relation to the artwork, the answer is c. where is the authenticity?, d. what is the value of the artwork?, and e. where is the subject matter? Since the artwork is a readymade object, Duchamp's hand is not physically present in the artwork, which raises questions about the role of the artist's hand in creating art. Additionally, the artwork challenges traditional notions of authenticity, as readymades are not considered unique objects. The value of the artwork is subjective and can be debated, and the absence of traditional subject matter further adds to the artwork's conceptual nature.
