Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.047\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(Nc1ccccc1Cl)Nc1cccnc1Cl
[b] CCC1=NN2C(=N)/C(=C/c3ccc(OS(=O)(=O)c4ccccc4)c(OC)c3)C(=O)N=C2S1
Answer: b. CCC1=NN2C(=N)/C(=C/c3ccc(OS(=O)(=O)c4ccccc4)c(OC)c3)C(=O)N=C2S1
