Task: Answer the multiple-choice question.
Query: Which compound exhibits a 2.232\% 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 CCc1nc(N)c(C#N)c(-c2ccccc2OC)c1C
b NC(=O)CN1C(=O)C(=O)N(Cc2cccc(C(F)(F)F)c2)C1=O
c O=[N+]([O-])c1cn(-c2nc(-c3ccco3)cc(C(F)(F)F)n2)cn1
Answer: c. O=[N+]([O-])c1cn(-c2nc(-c3ccco3)cc(C(F)(F)F)n2)cn1
