Question: Without a warrant, police officers searched the garbage cans in the alley behind a man's house and discovered chemicals used to make methamphetamine, as well as cooking utensils and containers with the man's fingerprints on them. The alley was a public thoroughfare maintained by the city, and the garbage was picked up once a week by a private sanitation company. The items were found inside the garbage cans in plastic bags that had been tied closed and further secured with tape. The man was charged in federal court with the manufacture of methamphetamine. Did the search of the garbage cans violate the Fourth Amendment? 
A: No, because the man had no reasonable expectation of privacy in garbage left in the alley.
B: No, because the probative value of the evidence outweighs the man's modest privacy claims in his garbage.
C: Yes, because the alley was within the curtilage of the man's home and entry without a warrant was unconstitutional.
D: Yes, because there is a reasonable expectation of privacy in one's secured garbage containers.
Please eliminate two incorrect options first, then think it step by step and choose the most proper one option.
