For a process, there are 25 samples taken from its output of variable sample size. There are total 234 defects in all the samples combined. If the total of all the sample sizes is 2450, what will be the value of the UCL in the case of variable-width control limits of p-chart?

• A. \(0.096+3\sqrt{0.096*\frac{0.904}{n_i}}\)
• B. \(0.087+3\sqrt{0.087*\frac{0.913}{n_i}}\)
• C. \(0.096-3\sqrt{0.096*\frac{0.904}{n_i}}\)
• D. \(0.087-3\sqrt{0.087*\frac{0.913}{n_i}}\)
