Final Answer :
B
Explanation :
The control limits for the -chart are typically calculated using the average range, so option A is incorrect. Option C and D provide incorrect formulae which could not be used to calculate control limits for the 11eabc4c_bb10_d3c9_8797_bb7033d93177_TB2972_11-chart. Therefore, option B is the best choice as it provides a correct formula to calculate control limits for the chart.
