What is the UCL of the acceptance control chart when the sample size n, the fraction nonconforming are specified?

• A. (UCL=USL- left(Z_ + frac{Z_ }{ sqrt{n}} right) )
• B. (UCL=USL+ left(Z_ - frac{Z_ }{ sqrt{n}} right) )
• C. (UCL=USL+ left(Z_ + frac{Z_ }{ sqrt{n}} right) )
• D. (UCL=USL- left(Z_ - frac{Z_ }{ sqrt{n}} right) )
