Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.251% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=C(Nc1ccccc1C(F)(F)F)c1ccccc1Br
b. COC(=O)C1=CO[C@@H](O[C@@H]2OC(CO)[C@@H](O)[C@@H](O)[C@@H]2O)C2C1CC[C@]2(C)O
c. CC(c1ccccc1)C1CC(=O)N(c2ccccc2)C1=O
Answer: b. COC(=O)C1=CO[C@@H](O[C@@H]2OC(CO)[C@@H](O)[C@@H](O)[C@@H]2O)C2C1CC[C@]2(C)O
