Task: Answer the multiple choice question.
Query: Which drug exhibits a -6.387% 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] COC(=O)[C@@]12CCCCN1[C@H](c1ccc(-c3cccc(Cl)c3)cc1)[C@H]1C(=O)N(C)C(=O)[C@H]12.O=C(O)C(F)(F)F
[b] CN1CCN(CCCNC(=O)c2ccc(CS(=O)(=O)c3ccc(Br)cc3)o2)CC1
[c] Cn1c(NCC(O)c2ccccc2)nc2c1c(=O)n(Cc1ccc(Cl)c(Cl)c1)c(=O)n2C
Answer: c. Cn1c(NCC(O)c2ccccc2)nc2c1c(=O)n(Cc1ccc(Cl)c(Cl)c1)c(=O)n2C
