Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.987\% 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 additional words.
Options:
a: CCOc1ccc(CN2C(=O)c3ccccc3C2=O)cc1C(=O)N1CCC(C(N)=O)CC1
b: O=C(CCc1cccc(Cl)c1)N1CCCC(Nc2ccccc2)C1
c: CC(C)(C)c1nnc(N/N=C/c2cc(Br)ccc2O)n(N)c1=O
d: COC(=O)C1=C(c2ccccc2)C[C@@H]2CC[C@H]1N2C(=O)NCc1ccco1
Answer: d. COC(=O)C1=C(c2ccccc2)C[C@@H]2CC[C@H]1N2C(=O)NCc1ccco1
