Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 12.863\% 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(COC(=O)c1ccc([N+](=O)[O-])o1)c1ccccc1
b CCC(=O)N1CCN(c2nc(CC)nc3sc4c(c23)CCCC4)CC1
c CCN(CC(=O)Nc1ccc(NC(C)=O)cc1)C(=O)c1ccc(C(=O)c2ccccc2)cc1
Answer: a. O=C(COC(=O)c1ccc([N+](=O)[O-])o1)c1ccccc1
