Problem statement: Answer the multiple choice question.
Question: Which compound has a 0.245\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a O=C(CSC1=NS(=O)(=O)c2cc(Cl)ccc2N1)Nc1ccccc1F
b COc1ccc(OCCN(C)C(=O)c2cccc(S(=O)(=O)N(C)c3ccccc3)c2)cc1
c CC1(OC(=O)C2CCCC2)C(=O)C=C2C=C(c3ccsc3)N(Cc3ccco3)C=C2C1=O
d O=C(c1ccco1)N1CCN(c2c([N+](=O)[O-])nn(-c3cccc(Cl)c3)[n+]2[O-])CC1
e CC(=O)c1c(C)n(-c2ccccc2Br)c2ccc(O)cc12
Answer: d. O=C(c1ccco1)N1CCN(c2c([N+](=O)[O-])nn(-c3cccc(Cl)c3)[n+]2[O-])CC1
