Task: Answer the multiple choice question.
Query: Which drug has a 3.680\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C(Nc1nnc(-c2ccccn2)o1)c1cccc(Cl)c1
b: CCOc1ccc(-c2c(=O)n(OCc3ccc([N+](=O)[O-])cc3)c3ccccc3[n+]2[O-])c(OCC)c1
c: CCOc1ccc(NC(=O)CN2CCN(S(=O)(=O)c3ccc(Cl)cc3)CC2)cc1
d: CC(=O)Nc1ccc(N2C(=O)CCC2=O)cc1C
e: Cc1ccc(N2CCN(c3ccc(C)cc3)C(CC(=O)O)C2=O)cc1
Answer: b. CCOc1ccc(-c2c(=O)n(OCc3ccc([N+](=O)[O-])cc3)c3ccccc3[n+]2[O-])c(OCC)c1
