Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.767\% 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 other words.
Options:
a O=C(COC(=O)c1cn(-c2ccccc2)nc1-c1cccs1)NC1CC1
b CCOC(=O)C1CCN(C(=O)COc2ccc(Br)cc2C)CC1
c O=[N+]([O-])c1ccc2nc(N3CCCC3)sc2c1
d O=C(NNS(=O)(=O)c1ccc(F)cc1)c1ccc([N+](=O)[O-])cc1Cl
Answer: a. O=C(COC(=O)c1cn(-c2ccccc2)nc1-c1cccs1)NC1CC1
