Task: Answer the multiple-choice question.
Query: Which compound exhibits a -0.447\% 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: CCc1cc(/C(Cc2ccc3ccccc3n2)=N\O)c(O)cc1O
b: O=C(Nc1cccc(Cl)c1N1CCCCC1)c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
c: O=C(C1=C[C@H](C2CC2)C[C@H](OCc2ccc(CO)cc2)O1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
d: O=C(c1ccco1)N1CCC(n2nnc3ccccc32)CC1
e: CCOc1ccccc1NC(=O)C(c1ccccc1)N1CCN(C(=O)c2ccco2)CC1
Answer: d. O=C(c1ccco1)N1CCC(n2nnc3ccccc32)CC1
