A husband decided to kill his wife by poisoning her. He asked his friend, a pharmacist, to obtain some curare, a deadly poison, and to give it to him without recording the transaction. Because the pharmacist suspected the husband's motive, she supplied the husband with a small quantity of Marvane, an antibiotic, instead of curare. Marvane is harmless if administered in small quantities, except for the less than 1 percent of the population who are allergic to the drug. The husband injected his wife with the Marvane while she slept. She was allergic to the drug and died from the injection. The pharmacist was distraught and confessed the entire affair to the police, explaining that she had failed to report the husband's conduct to the authorities because she feared that it would end their friendship if she did. In a common-law jurisdiction, the man is guilty of• (A) murder only.• (B) murder and conspiracy.• (C) attempted murder only.• (D) attempted murder and conspiracy.
