Task: Answer the multiple-choice question.
Question: Which compound exhibits a 0.802\% 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] CCO[C@H]1OC(C(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)=C[C@@H](c2cn(C(C)=O)c3ccccc23)[C@@H]1CCCO
[b] CC(=O)C1C(c2ccc(F)c(F)c2)NC(=O)NC1(O)C(F)(F)F
[c] O=C(c1ccc(Br)cc1)c1cc2ccc(O)cc2oc1=O
[d] O=C(CSCc1ccc(Cl)cc1)Nc1ccccc1O
Answer: a. CCO[C@H]1OC(C(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)=C[C@@H](c2cn(C(C)=O)c3ccccc23)[C@@H]1CCCO
