Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 8.987\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) C[C@@H]1NC(=O)/C(=C\c2ccccc2Cl)NC1=O
b) COc1ccc(-c2[nH]c(-c3cccc(OC)c3)nc2SCC(=O)NCc2ccco2)cc1
c) CCN(C(=S)Nc1cccc(C)c1)c1ccccc1
d) O=C(NCCNS(=O)(=O)c1ccccc1)c1ccc([N+](=O)[O-])cc1
Answer: d. O=C(NCCNS(=O)(=O)c1ccccc1)c1ccc([N+](=O)[O-])cc1
