Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.404\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1cc(NC(=S)NC(=O)c2cc(C)cc(C)c2)ccc1NC(=O)c1cccs1
b: O=C(Cn1c(O)c(N=NC(=O)c2ccccc2O)c2ccccc21)Nc1ccccc1
c: CCCCC(=O)Nc1ccc(NC(=O)c2ccc([N+](=O)[O-])cc2)cc1OC
d: CN(C)S(=O)(=O)c1ccc2c(c1)nc(CCC(=O)NCc1ccc(Cl)cc1)n2C
e: O=C(NC(=S)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1)c1ccccc1Cl
Answer: b. O=C(Cn1c(O)c(N=NC(=O)c2ccccc2O)c2ccccc21)Nc1ccccc1
