Task: Answer the multiple choice question.
Query: Which compound has a 12.892\% 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(CN1c2ccccc2Sc2ccccc21)N/N=C/c1ccc(Cl)cc1Cl
b: CCOC(=O)C1CCN(C(=O)Cc2ccc(OC)c(OC)c2)CC1
Answer: a. O=C(CN1c2ccccc2Sc2ccccc21)N/N=C/c1ccc(Cl)cc1Cl
