Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.342\% 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 other words.
Options:
a: CCCCCCc1c(O)nc(SCCN2CCOCC2)[nH]c1=O.Cl
b: Cc1cc(C(F)F)n2nc(C(=O)Nc3sc4c(c3C(N)=O)CCC4)nc2n1
c: CN1CCN(C(N)=NC(=O)c2ccccc2)CC1
d: COC(=O)c1ccc(NC(=O)CSc2nnc(C)n2-c2ccccc2)cc1
e: COCc1[nH][nH]c(=O)c1C=Nc1ccc(Cl)cc1
Answer: b. Cc1cc(C(F)F)n2nc(C(=O)Nc3sc4c(c3C(N)=O)CCC4)nc2n1
