Task: Answer the multiple-choice question.
Question: Which compound has a 20.520\% 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: Cc1cc(C)c(S(=O)(=O)N2C=CC(C(F)(F)F)=NCC2)c(C)c1
b: O=C(O)CSc1nnc(Cn2cnc3ccccc32)n1CCc1ccccc1
c: COc1ccc(-c2nnc(SCc3ccccc3F)o2)cc1
d: COC(=O)CN(c1ccc(OCc2ccccc2)cc1)S(C)(=O)=O
e: CCOC(=O)Cn1c(-c2ccccc2)nc2ccccc2c1=O
Answer: b. O=C(O)CSc1nnc(Cn2cnc3ccccc32)n1CCc1ccccc1
