Using a standard normal table or calculator, we find that P(z < -1.09) = 0.1379 and P(z < 1.06) = 0.8531. Thus, P(-1.09 < z < 1.06) = P(z < 1.06) - P(z < -1.09) = 0.8531 - 0.1379 = 0.7152. Rounded to four decimal places, this gives us the closest answer choice of C, which is 0.7176. Therefore, C is the correct answer.
