To maintain an identical Average Outgoing Quality Limit (AOQL) for the purchasing company, the same sampling plan should be used for both lots. Therefore, option A and B are eliminated. Option C would result in a larger sample size, which may not be feasible under time constraints. Therefore, the best option would be to take a random sample of 50 from each lot, as per the original sampling plan, and accept or reject each lot based on the results. This will ensure that the same level of quality control is maintained for both lots and the AOQL remains identical.
