Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.604\% 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) COc1ccc(NC(=O)Nc2c(C)n(C)n(-c3ccccc3)c2=O)c(OC)c1
b) CCNC(=S)NCc1ccc2[nH]c(C)cc2c1
c) O=C(CNC1CCCC1)Nc1cc(Cl)ccc1[N+](=O)[O-].O=C(O)C(=O)O
Answer: c. O=C(CNC1CCCC1)Nc1cc(Cl)ccc1[N+](=O)[O-].O=C(O)C(=O)O
