Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.973\% human ether-à-go-go related gene (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: O=S(=O)(Nc1nc2ccccc2[nH]1)c1ccc2ccccc2c1
b: CCOC(=O)C(C)Sc1nc(-c2ccco2)cc(C(F)(F)F)c1C#N
c: Cc1csc(NC(=O)CSc2nncn2C)n1
d: COc1ccccc1C(=O)NC(=S)Nc1ccc(NC(=O)c2ccco2)cc1
e: CC(C)C(=O)Nc1cccc(NC(=O)c2ccc([N+](=O)[O-])cc2Cl)c1
Answer: b. CCOC(=O)C(C)Sc1nc(-c2ccco2)cc(C(F)(F)F)c1C#N
