Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.269\% 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 other words.
Options:
a) CCC(=O)N(Cc1cc2cccc(C)c2[nH]c1=O)c1ccccc1OC
b) O=[N+]([O-])c1cccc(/C=C2\CCC(/C=N/Nc3ccc4ccccc4n3)=C2N2CCOCC2)c1
c) O=C(O)c1ccccc1N/C=C\[N+](=O)[O-]
d) CC(C)(C)c1ccc(OCC(=O)N/N=C/c2cc(Br)ccc2OC(=O)c2ccco2)cc1
Answer: d. CC(C)(C)c1ccc(OCC(=O)N/N=C/c2cc(Br)ccc2OC(=O)c2ccco2)cc1
