Task: Answer the multiple-choice question.
Query: Which compound exhibits a 12.524\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(COc1ccc([N+](=O)[O-])cc1)Nc1ccc(NC(=O)c2ccccc2)cc1
b) CCN1/C(=C\C(C)=O)Sc2ccc(OC)cc21
c) COc1ccc(C/C(C)=N/NC(=O)c2cc(C)oc2C)cc1
Answer: b. CCN1/C(=C\C(C)=O)Sc2ccc(OC)cc21
