Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.628\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=c1cc(-c2ccc(O)cc2)oc2c([C@@H]3O[C@H](CO)[C@@H](O)[C@H](O)[C@H]3O)c(O)c([C@@H]3O[C@H](CO)[C@@H](O)[C@H](O)[C@H]3O)c(O)c12
[b] CCOC(=O)c1c(NC(=O)CNCCOC)sc2c1CCCC2
[c] CCCCNC(=S)NNC(=O)c1cc(-c2ccncc2)nc2ccccc12
Answer: a. O=c1cc(-c2ccc(O)cc2)oc2c([C@@H]3O[C@H](CO)[C@@H](O)[C@H](O)[C@H]3O)c(O)c([C@@H]3O[C@H](CO)[C@@H](O)[C@H](O)[C@H]3O)c(O)c12
