Task: Answer the multiple choice question.
Question: Which compound has a -0.253% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1cc(/C=N\NC(=O)c2ccc(-c3ccccc3)cc2)cc(Br)c1O
b: CCOc1ccc(N(CC(=O)OC)S(=O)(=O)c2ccc(OC)c(OC)c2)cc1
c: COc1cc(OC)c2c(=O)cc(-c3ccccc3)oc2c1
d: O=C(NCCc1ccccc1)c1cccc([N+](=O)[O-])c1
Answer: d. O=C(NCCc1ccccc1)c1cccc([N+](=O)[O-])c1
