Task: Answer the multiple-choice question.
Question: Which drug has a -6.394\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(NCc1ccco1)C1(S(=O)(=O)c2ccccc2)CC=CC1
b. CC(=O)Nc1cccc(NC(=O)COc2ccccc2C)c1
c. COc1ccc(N(CC(=O)NCCSCc2ccco2)S(=O)(=O)c2ccc(C)cc2)cc1
d. COc1ccc([N+](=O)[O-])cc1NC(=O)C(C)OC(=O)C1CC(=O)N(Cc2ccco2)C1
Answer: d. COc1ccc([N+](=O)[O-])cc1NC(=O)C(C)OC(=O)C1CC(=O)N(Cc2ccco2)C1
