Problem statement: Answer the multiple-choice question.
Question: Which drug has a 4.769\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a Cc1ccc2cc(C3CC(c4ccco4)=NN3S(C)(=O)=O)c(Cl)nc2c1
b CC1CC(OC(=O)c2ccccc2)(c2ccccc2)C(C)CN1C
c O=C(CNc1cccc2ccccc12)c1ccc([N+](=O)[O-])cc1
d COc1ccc(/C=N/NC(C)(C)C)c(OC)c1.Cl
e CN(C(=O)COC(=O)/C=C/c1cccc([N+](=O)[O-])c1)C1CCS(=O)(=O)C1
Answer: c. O=C(CNc1cccc2ccccc12)c1ccc([N+](=O)[O-])cc1
