Task: Answer the multiple-choice question.
Query: Which compound has a 9.453\% 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. NC(=O)CC[C@H](NC(=O)c1ccc(F)cc1)C(=O)OCC(=O)Nc1ccc(N2CCOCC2)cc1
b. CCN(CC)S(=O)(=O)c1cccc(NC(=O)CCNC(=O)c2ccc([N+](=O)[O-])cc2)c1
c. CC(C(N)=O)N1c2cccc3cccc(c23)S1(=O)=O
d. O=C(C[N+]12CCN(CC1)CC2)NCCc1ccc(Cl)cc1Cl.[Cl-]
Answer: c. CC(C(N)=O)N1c2cccc3cccc(c23)S1(=O)=O
