Problem statement: Answer the multiple choice question.
Query: Which compound has a 12.766\% hERG inhibition at 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)COC(=O)c1ccc(Cl)c(S(=O)(=O)N(Cc2ccccc2)c2ccc(Cl)cc2)c1
(b) COCCN1C(=O)N[C@@H](c2cccs2)C(C(C)=O)=C1C
(c) CCCCOC(=O)Nc1cc(C)c(Cl)cc1OC
(d) S=C(NCc1cccnc1)Nc1ccc(Oc2ccc(Cl)cc2)cc1
Answer: b. COCCN1C(=O)N[C@@H](c2cccs2)C(C(C)=O)=C1C
