Task: Answer the multiple choice question.
Query: Which drug has a 24.094\% 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) COc1ccc(S(=O)(=O)c2nnn(-c3cccc(Cl)c3)c2N)cc1
(b) CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](C(C)(C)C)[C@H]1CCCO
(c) CC(O)/C=C/C1OC(=O)CC1Nc1ccc(C=O)cc1
(d) COc1ccc(Cl)cc1N1C(=O)C2CCCN2C1c1ccccc1F
(e) COc1cc(/C=N/N=C(\N)c2nonc2N)cc(OC)c1O
Answer: b. CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](C(C)(C)C)[C@H]1CCCO
