When the EWMA charts are in operation for quite a long period, what will be the value of the UCL of the chart?

a) UCL=\(μ_0+Lσ\sqrt{\left\{\frac{λ}{2-λ}\right\}}\)
b) UCL=\(μ_0-3Lσ\sqrt{\left\{\frac{λ}{2-λ}\right\}}\)
c) UCL=\(μ_0+2Lσ\sqrt{\left\{\frac{λ}{2-λ}\right\}}\)
d) UCL=\(μ_0-Lσ\sqrt{\left\{\frac{λ}{2-λ}\right\}}\)
b) UCL=\(μ_0-3Lσ\sqrt{\left\{\frac{λ}{2-λ}\right\}}\)
c) UCL=\(μ_0+2Lσ\sqrt{\left\{\frac{λ}{2-λ}\right\}}\)
d) UCL=\(μ_0-Lσ\sqrt{\left\{\frac{λ}{2-λ}\right\}}\)
