Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.846\% 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 additional words.
Options:
[a] COc1ccc(C2=C/C(=C\c3ccccc3OC(C)=O)C(=O)O2)cc1
[b] O=C(CN(C(=O)c1ccccc1Cl)C1CCCCC1)Nc1ccc(Cl)c([N+](=O)[O-])c1
[c] O=c1c2ccccc2nnn1CCO
[d] CC(=O)N1CCN(Cc2nc3cc(NC(=O)c4ccccc4Cl)ccc3n2C)CC1
[e] CC(=O)C1=C(O)CC(C)(C)CC1=NCCc1nc2ccccc2[nH]1
Answer: b. O=C(CN(C(=O)c1ccccc1Cl)C1CCCCC1)Nc1ccc(Cl)c([N+](=O)[O-])c1
