Task: Answer the multiple-choice question.
Question: Which drug has a 3.244\% 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 additional words.
Options:
a) CCOc1ccc(S(=O)(=O)N(CC)CC(=O)NCc2ccco2)cc1C
b) Cc1cccc(N2CC(C(=O)Nc3nnc(SCCC4OCCO4)s3)CC2=O)c1
c) O=C(Cn1c(=O)cnc2ccccc21)N1CCN(S(=O)(=O)c2cccc([N+](=O)[O-])c2)CC1
d) NC(=O)CC(NC(=O)c1ccc(Br)cc1)c1ccc(NC2CCCCC2)c([N+](=O)[O-])c1
Answer: c. O=C(Cn1c(=O)cnc2ccccc21)N1CCN(S(=O)(=O)c2cccc([N+](=O)[O-])c2)CC1
