The upper control limit (UCL) for an R chart is calculated using the formula UCL = D4 * R-bar, where D4 is a constant that depends on the sample size. Without specific sample size or R-bar values, we assume the given options are calculated using the correct constants, and 10.66 is the highest value, typically representing the UCL.
