Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.292% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=c1[nH]c(=O)n(C2CCCO2)cc1F
[b] O=[N+]1C=C(c2ccccc2)N([O-])C2CCCCC21
[c] CCOC(=O)N(CC)OC(=O)Nc1ccc(Cl)cc1
Answer: a. O=c1[nH]c(=O)n(C2CCCO2)cc1F
