Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.777\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COc1ccc(NC(=O)c2cccc(C(=O)Nc3ccc(OC)cc3)n2)cc1
[b] CC1(C(=O)Nc2ccc3c(c2)OCCO3)CC1(Cl)Cl
[c] Cn1cc([N+](=O)[O-])c(C(=O)Nc2cc(Oc3cccnc3)cc([N+](=O)[O-])c2)n1
Answer: b. CC1(C(=O)Nc2ccc3c(c2)OCCO3)CC1(Cl)Cl
