Answer: (D)

Verified step by step guidance

1. Understand that a supply schedule shows the relationship between the price of a good and the quantity supplied, holding other factors constant.
2. Identify the factors typically held constant when constructing a supply schedule: number of sellers, prices of inputs, and technology used in production are usually held constant.
3. Recognize that the price of the good itself is the variable that changes in a supply schedule to show how quantity supplied responds.
4. Therefore, the factor NOT held constant when constructing a supply schedule is the price of the good itself, because it is the independent variable that affects quantity supplied.
5. Summarize that all other factors (number of sellers, input prices, technology) are held constant to isolate the effect of the good's price on quantity supplied.
