user: Read the case excerpt and choose the best holding from the options. Case excerpt: been committed before Agent Faria intervened, Valencia-Vergara had the opportunity to proceed to trial, but chose to plead guilty, and he was represented during his plea and sentencing hearings by his attorney. Based on these considerations, Agent Faria’s conduct, though reprehensible, did not rise to the level of fundamental unfairness and outrageousness contemplated by this Court’s precedent. See id. at 868-69. Moreover, as the magistrate judge noted, neither this Court nor the Supreme Court has reversed a conviction because of a failure to dismiss a case based on government misconduct, and this case is not one of the rare instances in which government conduct was so outrageous that it violated due process. See United States v. Tobias, 662 F.2d 381, 385-87 (5th Cir. Unit B Nov.1981) (<HOLDING>). Moreover, even if Valencia-Vergara had shown Options: A. holding that when the government acts to enforce public rights the mere fact that the government has no pecuniary interest in the controversy is not sufficient to exclude it from the courts B. holding that whether error in failing to ask a question about bias in favor of law enforcement testimony requires reversal hinges on such factors as the importance of the government agents testimony to the case as a whole the extent to which the question concerning the venire persons attitude toward government agents is covered in other questions the extent to which the credibility of the government agentwitness is put into issue and the extent to which the testimony of the government agent is corroborated by nonagent witnesses internal quotation marks and citation omitted C. holding where 1 the government provided the defendant with all the necessary drugmaking materials 2 the government provided instructions on how to make the drugs and 3 the defendant sought out the materials and help from the undercover government agents the case set the outer limits to which the government may go in the quest to ferret out and prosecute crimes but the governments conduct did not rise to the level of a due process violation D. holding that the defendant failed to demonstrate government acquiescence in part because he never reported alleged gang incidents to the government and therefore could not prove that the government was even aware of a problem E. holding that the district court did not err in instructing the jury not to draw any adverse inferences from the governments failure to call a witness because the witness did not have a relationship with the government such that one would expect him to give testimony in favor of the government

assistant: The best answer is C. holding where 1 the government provided the defendant with all the necessary drugmaking materials 2 the government provided instructions on how to make the drugs and 3 the defendant sought out the materials and help from the undercover government agents the case set the outer limits to which the government may go in the quest to ferret out and prosecute crimes but the governments conduct did not rise to the level of a due process violation
