Task: Answer the multiple-choice question.
Query: Which drug has a 16.583\% 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.) O=C(O)Cn1c(-c2ccccc2)cc2ccccc21
b.) O=C(NNS(=O)(=O)c1ccc(F)cc1)c1ccccc1O
