Task: Answer the multiple-choice question.
Question: Which compound exhibits a 15.970\% 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 additional words.
Options:
a: CCOc1ccc(CO[C@@H]2O[C@H](CO)[C@@H](O)[C@H](O)[C@H]2NC(C)=O)cc1OC
b: CC(NC(=O)Nc1ccccc1C(F)(F)F)C1CCCO1
c: CCOC(=O)c1ccc(NC(=O)c2cc(OC)c(OC)c(OC)c2Br)cc1
Answer: a. CCOc1ccc(CO[C@@H]2O[C@H](CO)[C@@H](O)[C@H](O)[C@H]2NC(C)=O)cc1OC
