Task: Answer the multiple-choice question.
Question: Which drug exhibits a 18.269\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(NCc1ccccc1)NC(=O)c1ccccc1F
b CN1CCN(c2nc(N3CCN(CCO)CC3)nc3ccccc23)CC1.Cl
c Nc1cccnc1S(=O)(=O)c1ccccc1
