Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 19.551\% 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, or c without using any other words.
Options:
a. O=C(Nc1ccc(F)c(F)c1)c1ccco1
b. O=C1CC(C(=O)N2CCOCC2)C2(CCCCC2)O1
c. CCOC(=O)c1sc(NC(=O)CSc2nc(-c3ccco3)cc(C(F)(F)F)n2)c(C#N)c1C
Answer: b. O=C1CC(C(=O)N2CCOCC2)C2(CCCCC2)O1
