Explanation:

In microbiology, a culture that contains only a single known species or type of microorganism is defined as a pure culture. The term "aseptic" relates to techniques to prevent contamination, "clean" is a general term for lack of dirt, and "single" is not the standard term used in this context for microbial cultures. So the correct term is "pure".

Answer:

D. pure (assuming the last option is labeled D; if the original labels were different, adjust the label but the text is "pure")
