Which of the following statements violates the sunk cost principle? T. I called customer support because my digital camera does not work anymore, and T have been on hold for a few minutes. I am wondering whether I should give up and try again the next day, or whether I should stay on the line and keep waiting. As I make that decision, I consider how much time 1 have already spent waiting, because it helps me think of how much longer I might need to wait before I can speak to a representative. II. When selling my small business, I should think about how much I paid to purchase the company 5 years ago because it may change my tax bracket and affect my profit.

a. I only

b. II only

c. Both I and II

d. Neither I nor II
