A Type I error occurs when a good lot is rejected, meaning that the quality of the lot is actually acceptable but it is mistakenly deemed unacceptable. This can lead to unnecessary costs and delays in the production process. Accepting a bad lot (option A) or rejecting a bad lot (option C) are actually desirable outcomes as they avoid producing defective products. Accepting a good lot (option D) is also an acceptable outcome.
