Task: Answer the multiple choice question.
Question: Which drug exhibits a -61.192% 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: COc1ccc(NC(=O)Cn2cc(C(=O)C3CC3)c3ccccc32)cc1
b: O=C(NC(=S)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1)c1ccco1
c: O=C(CCNS(=O)(=O)c1ccccc1)Nc1ccccc1
d: COc1ccc(N2C(=O)C3C(C2=O)C(C(=O)c2ccc(Cl)cc2)N2CCCC32)cc1
Answer: b. O=C(NC(=S)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1)c1ccco1
