Task: Answer the multiple choice question.
Query: Which compound has a 8.939% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCOc1cccc(-c2cc(C(=O)N3N=C(C)CC3(O)C(F)F)c3ccccc3n2)c1
b: O=C(Cn1ccc(C(F)(F)F)n1)NNC(=O)c1ccco1
c: COc1ccc(Oc2cc(NC(=O)c3nn(C)cc3[N+](=O)[O-])cc([N+](=O)[O-])c2)cc1
Answer: b. O=C(Cn1ccc(C(F)(F)F)n1)NNC(=O)c1ccco1
