Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.518\% 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: Nn1c(SCc2cccc(F)c2)nnc1-c1ccncc1
b: CC(C)[C@]1(c2ccccc2)ON(c2ccccc2C(F)(F)F)C1=O
c: Cc1ccc(SCCC(=O)Nc2cccc(N(C)S(C)(=O)=O)c2)cc1
d: Nc1c(C(=O)c2ccc(Cl)cc2)sc2nsc(SCCN3CCOCC3)c12
e: CCOC(=O)CSc1nc(N)c(C#N)c(-c2ccc(OCC)cc2)c1C#N
Answer: b. CC(C)[C@]1(c2ccccc2)ON(c2ccccc2C(F)(F)F)C1=O
