Task: Answer the multiple choice question.
Question: Which compound has a 18.451% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(CSc1nnc(-c2ccc(S(=O)(=O)N3CCOCC3)cc2)o1)c1ccccc1F
b: O=C(NCc1cccnc1)Nc1cccc(NC(=O)NCc2cccnc2)c1F
Answer: b. O=C(NCc1cccnc1)Nc1cccc(NC(=O)NCc2cccnc2)c1F
