Task: Answer the multiple choice question.
Query: Which compound exhibits a 9.004\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(CN(CC1CCCO1)C(=O)CCC(=O)Nc1nccs1)NCc1ccccc1
(b) CCC(=O)N1CCc2cc(Br)cc(S(=O)(=O)N3CCN(C(=O)c4ccco4)CC3)c21
(c) C/C=C(/C)C(=O)O[C@@H]1c2cc3c(c4c2[C@@]2(CO4)C(=O)C(OC)=C(OC)C=C2C[C@@H](C)[C@H]1C)OCO3
(d) CCCCNC(=O)CCn1c(=O)c2ccccc2n(Cc2ccccc2C)c1=O
Answer: a. O=C(CN(CC1CCCO1)C(=O)CCC(=O)Nc1nccs1)NCc1ccccc1
