Task: Answer the multiple-choice question.
Query: Which compound exhibits a -20.844% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CN(C)c1cc[n+](CC(=O)Nc2cc(C(F)(F)F)ccc2Cl)cc1.[Cl-]
b) CC(=O)c1ccc2c(c1)C1C(Cl)C(Sc3ccccc3[N+](=O)[O-])CC1C(C(=O)O)N2
c) CN(Cc1ccccc1)C(=O)CN(C1CCCCC1)S(C)(=O)=O
d) COc1ccc(CCNC(=O)CC2Nc3cc(C)c(C)cc3NC2=O)cc1OC
Answer: b. CC(=O)c1ccc2c(c1)C1C(Cl)C(Sc3ccccc3[N+](=O)[O-])CC1C(C(=O)O)N2
