The integral of sin(x) from 0 to pi/2 is equal to -cos(x) evaluated from 0 to pi/2. Plugging in these values, we get -cos(pi/2) - (-cos(0)) = -0 - (-1) = 1. However, since we are asked to evaluate the absolute value of the integral, the answer is 1, which is equivalent to choice C. A graphing utility can be used to verify this result.
