Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -0.267% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cc1nc(-c2nnc(SCC(=O)Nc3cc(Cl)cc(Cl)c3)n2C)cs1
b: S=c1[nH]cc(-c2ccc(Cl)cc2)n1-c1ccccc1
c: CC(C)CN(C(=O)CN1CCN(c2ccc([N+](=O)[O-])cc2)CC1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
Answer: b. S=c1[nH]cc(-c2ccc(Cl)cc2)n1-c1ccccc1
