Answer

Answer:

B. Parts are chosen at random from the many parts made each day.

Brief Explanations:

A convenience sample is non - random. Random selection is not convenience sampling. The other options (inspecting first parts after lunch, at end of day a container, first parts after start of day) are convenience samples as they are based on easy access or specific time - based convenience, while random selection is not.
