Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.697\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C(c1ccc(COc2c(F)c(F)c(F)c(F)c2F)o1)N1CCOCC1
[b] CN(C)C=Nc1ccc2nc3c(cc2c1)[nH]c1ccccc13
[c] COc1ccccc1N(Cc1ccccc1)S(=O)(=O)c1cccc(C(=O)Nc2ccccn2)c1
Answer: b. CN(C)C=Nc1ccc2nc3c(cc2c1)[nH]c1ccccc13
