Task: Answer the multiple-choice question.
Query: Which compound has a -2.029% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1cc(/C=C/C(=O)OCC(=O)Nc2cc(S(=O)(=O)N3CCCCC3)ccc2C)ccc1O
(b) O=C(Nc1nc(-c2ccc(-c3ccccc3)cc2)cs1)C1=COCCO1
(c) CCCn1c(C)cc(-c2csc(NC(=O)CCc3nc4ccccc4c(=O)[nH]3)n2)c1C
(d) C/C(N)=C(/C#N)C(=O)COC(=O)CNC(=O)c1ccc(Cl)cc1Cl
Answer: b. O=C(Nc1nc(-c2ccc(-c3ccccc3)cc2)cs1)C1=COCCO1
