Task: Answer the multiple choice question.
Query: Which compound exhibits a -22.031\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1cccc(-n2nc3c(=O)n(Cc4ccccc4Cl)nc(C)c3c2C)c1
b: O=C(CSc1nnnn1-c1ccccc1)N1CCN(C(=O)c2ccco2)CC1
c: Cc1ccc(C)c(OCC(O)CN2CCc3ccccc3C2)c1C.Cl
d: COC(=O)/C(=C\c1cc(OC)c(OC)c(OC)c1)c1nc2ccccc2[nH]1.Cl
e: Cn1c(=O)c(Oc2ccc(Cl)cc2)c(O)c2ccccc21
Answer: b. O=C(CSc1nnnn1-c1ccccc1)N1CCN(C(=O)c2ccco2)CC1
