Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -40.688\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) Cl.Oc1ccccc1CNCc1ccccc1
b) CC1SC(c2ccccc2)N(CC(O)c2ccc([N+](=O)[O-])cc2)C1=O
c) COc1ccccc1C(=O)Nc1ccc(-c2nnc(SCC(=O)O)n2C)cc1
d) Cc1cc(/C=N/Nc2nc(N)ncc2[N+](=O)[O-])c(C)n1-c1cccc(C(F)(F)F)c1
e) Cc1ccccc1N1C(=O)C(Oc2ccc(Cl)cc2)C1CNC(C)(C)C
Answer: b. CC1SC(c2ccccc2)N(CC(O)c2ccc([N+](=O)[O-])cc2)C1=O
