Task: Answer the multiple-choice question.
Question: Which compound exhibits a 4.671\% human ether-à-go-go related gene (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.O=c1ccc2cc(O[C@@H]3O[C@@H](CO)[C@H](O)[C@@H](O)[C@@H]3O)c(O)cc2o1
[b] O=C(Nc1ccc(F)cc1F)c1ccc(-n2cccn2)c([N+](=O)[O-])c1
[c] COC(=O)c1c(NC(=O)c2ccccc2OC)sc(C(=O)N2CCOCC2)c1C
[d] Cc1c(C(=O)N(C)c2ccccc2Cl)cnn1-c1ccccc1
Answer: c. COC(=O)c1c(NC(=O)c2ccccc2OC)sc(C(=O)N2CCOCC2)c1C
