How much does the arithmetic and geometric average rates of return differ, assuming that the rate of return is a constant 6% annually? (a) The arithmetic return is 6.00% while the geometric return is 5.54%. (b) The arithmetic return is 5.54% while the geometric return is 6.00%. (c) The constant rate has a standard deviation of 0; therefore the arithmetic and the geometric returns will be the same. (d) The arithmetic and the geometric returns will be the same since the standard deviation of the returns equals 1
