Task: Answer the multiple choice question.
Question: Which compound has a -2.233\% human ether-à-go-go related gene (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: Cc1cc2oc(=O)cc(CN3CCOCC3)c2cc1C
b: C=CCn1c(Sc2ccc(S(=O)(=O)N3CCOCC3)cc2[N+](=O)[O-])nnc1C1CCCCC1
c: O=C1c2cccc3cccc(c23)C(=O)N1OS(=O)(=O)c1ccccc1
d: FC(F)(F)c1ccc2c(c1)N1CCCC1CN2
e: COc1ccc(NS(=O)(=O)c2ccc(-c3coc(C)n3)cc2)cc1OC
Answer: d. FC(F)(F)c1ccc2c(c1)N1CCCC1CN2
