In statistical quality control, α (alpha) is the probability of rejecting good product or the Producer's Risk and β (beta) is the probability of accepting bad product or the Consumer's Risk.

If α=0.05, then the probability of rejecting good product or the Producer's Risk is 5% and if β=0.10, then the probability of accepting bad product or the Consumer's Risk is 10%.

This means that the customer expects to accept lots that exceed the LTPD about 10% of the time (since the LTPD is the maximum percentage of defects the customer is willing to accept) and the company expects to reject lots that are as good or better than the AQL about 5% of the time (since the AQL is the maximum percentage of defects the company is willing to tolerate).

Therefore, the best choice is C.
