Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 8.688\% 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=c1c2ccccc2nnn1COc1cccc(Cl)c1
[b] O=C(NNc1ccc(Cl)nn1)c1ccc(Cl)cc1
[c] O=C(Oc1ccc(/C=N/Nc2ccccc2)cc1)c1ccccc1
Answer: a. O=c1c2ccccc2nnn1COc1cccc(Cl)c1
