Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.200\% 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] CC1(C)CC(=O)C2=C(C1)Oc1ncn(CCCn3ccnc3)c(=N)c1C2c1ccccc1
[b] CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2c1cn(-c2ccccc2)nc1-c1ccc(F)cc1
[c] O=C(Nc1ccc(S(=O)(=O)N2CCOCC2)cc1)c1ccc([N+](=O)[O-])o1
Answer: b. CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2c1cn(-c2ccccc2)nc1-c1ccc(F)cc1
