Task: Answer the multiple-choice question.
Query: Which compound exhibits a -7.279% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(NC(NC(=O)c1ccccc1)c1cccc([N+](=O)[O-])c1)c1ccccc1
b CCc1ccc(/C=N/NC(=O)c2c[nH]c3ccccc23)s1
c CN(C)S(=O)(=O)N1CCN(c2cccc(Cl)c2)CC1
d Cc1ccc(NC(=S)NNC(=O)Cn2nc([N+](=O)[O-])cc2C)cc1
Answer: c. CN(C)S(=O)(=O)N1CCN(c2cccc(Cl)c2)CC1
