By using a standard normal table or calculator, we can find the area under the curve between z = -2.05 and z = 2.05 is approximately 0.9596. Therefore, the best choice is C. Using a standard normal distribution table, we can find the area to the left of z = 2.05 is 0.9798, and the area to the left of z = -2.05 is 0.0202. The area between these two z-scores is the difference between these two values: 
0.9798 - 0.0202 = 0.9596. Therefore, the answer is (C).
