Task: Answer the multiple-choice question.
Query: Which drug has a 13.009\% human ether-à-go-go related gene (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] CCc1nc(N2CCCC(C)C2)c2oc3ccccc3c2n1.Cl
[b] O=C1OC(c2ccc(F)cc2)=C/C1=C\c1ccc([N+](=O)[O-])o1
[c] Cc1nc(-c2ccc(Br)cc2)ccc1C(=O)O
Answer: b. O=C1OC(c2ccc(F)cc2)=C/C1=C\c1ccc([N+](=O)[O-])o1
