The sentence that is NOT an example of plagiarism is:
D "With a black exoskeleton and measuring approximately 5 mm, the mountain pine beetle is native to the forests of western North America from Mexico to central British Columbia."
This sentence rephrases the information from the original source without directly copying the text or using quotes, thus avoiding plagiarism. In contrast, options A, B, and C either duplicate the original text verbatim or use quotes without proper attribution.
