Two normal curves will always have the same shape, which is characterized by the bell curve. The only differences will be in the mean (which shifts the curve left or right) and the standard deviation (which determines how spread out the curve is). Therefore, the correct choice is C, as this option includes both the mean and standard deviation as the only distinguishing factors between the two normal curves. Skewness and kurtosis are not characteristics of normal distributions, as they are typically associated with distributions that are not symmetrical.
