Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.662% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(c1ccc(Cl)c(F)c1F)N1CCCC1
[b] CN(C(=O)c1nn(C)cc1Br)C12CC3CC(CC(C3)C1)C2
Answer: a. O=C(c1ccc(Cl)c(F)c1F)N1CCCC1
