The half-life of carbon-14 is approximately 5,730 years. Since the bone contains 1/8 of the carbon-14 found in living animals today, it can be inferred that it has undergone 3 half-lives (1/2 * 1/2 * 1/2 = 1/8). Therefore, the approximate age of the bone is 5,730 years * 3 = <<5730*3=17190>>17,190 years. The answer is c) 17,190 years.
