Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.692\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) COc1ccc(N=Nc2[nH]c3ccc(C)cc3c2O)cc1
b.) O=c1cc(-c2ccc(O)cc2)oc2c(C3O[C@H](CO)[C@@H](O)[C@H](O)[C@H]3O)c(O)cc(O)c12
Answer: b. O=c1cc(-c2ccc(O)cc2)oc2c(C3O[C@H](CO)[C@@H](O)[C@H](O)[C@H]3O)c(O)cc(O)c12
