Problem statement: Answer the multiple choice question.
Question: Which compound has a 20.842\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) Cc1cc(C)cc(N2C(=O)CCN(Cc3ccccc3)C2=O)c1
(b) Cc1cc(N=Nc2ccc(Cl)cc2)cc(CN2CCOCC2)c1O
(c) COC(=O)[C@@H]1C[C@@H]2CC[C@@H](O)C[C@@H]2N1Cc1ccccc1OS(=O)(=O)c1ccc(C)cc1
(d) CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](c2ccccc2)[C@H]1CCCO
(e) CCOC(=O)Cn1c(=NC(=O)C2COc3ccccc3O2)sc2cc(S(N)(=O)=O)ccc21
Answer: d. CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](c2ccccc2)[C@H]1CCCO
