Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 16.287\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a Cc1ccc(C23CC4CC(CC(NC(=O)NC(C)(C)CO)(C4)C2)C3)cc1
b O=C(Nc1ccc(C(F)(F)F)cc1)C1CCN(S(=O)(=O)c2ccc(N3CCCC3=O)cc2)CC1
c COc1ccc(C(=O)NCCS(=O)(=O)NCc2ccccc2OC)cc1
d O=C(NNC(=S)Nc1ccc(Cl)c(Cl)c1)c1cccc([N+](=O)[O-])c1
Answer: d. O=C(NNC(=S)Nc1ccc(Cl)c(Cl)c1)c1cccc([N+](=O)[O-])c1
