I thought it was D) 2.12, but I'm not entirely confident either.

I think the answer might be B) 1.27 because the Cpk calculation should include those factors.

Yes, it does. The process average is 94, spread is 22, and the limits are 80 and 125.

I agree, Cpk can be confusing. I think the formula involves the average, spread, and limits.
