Task: Answer the multiple choice question.
Question: Which drug has a 13.704\% 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) COc1c(Cl)cccc1-c1cn2ccccc2n1
b) O=C(O)CCCC(=O)Nc1ccc(OCc2nc3ccccc3s2)cc1
