When introducing a tea to a guest, a tea dealer said: "This tea is produced in Yunshan, and the famous Yunshan tea is produced in Yunshan, so this is the authentic Yunshan tea. ". Which of the following is most similar to the logic when the dealer introduced tea:. ['The students in the third class are hard-working and hard-working. Xiao Li is a student in the third class, so Xiao-li is hard-working and hard-working.', 'The Flying Car is produced in a certain country. The car just now is not a Flying Car, so it must not be made in China.', 'All drivers must have a driving license, Xiao Zheng has a driving license, so Xiao Zheng is the driver.', 'A good doctor needs to have superb medical skills and noble medical ethics. Xiao Chen has both, so he is a good doctor.']
