Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.318\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(CSc1cccc[n+]1[O-])Nc1ccccc1Oc1ccccc1
[b] Cc1c(C)c2ccc(OC(C)C(=O)N[C@@H](Cc3c[nH]c4ccccc34)C(=O)O)c(C)c2oc1=O
[c] O=C1CSC(c2ccccc2[N+](=O)[O-])N1c1ccc(O)cc1
[d] O=C(Nc1cccc(Cl)c1)C1C2CCC3C(CCC21)C3(Cl)Cl
Answer: b. Cc1c(C)c2ccc(OC(C)C(=O)N[C@@H](Cc3c[nH]c4ccccc34)C(=O)O)c(C)c2oc1=O
