Task: Answer the MCQ question.
Question: Which compound exhibits a 21.422\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1c(O[C@@H]2O[C@H](CO)[C@@H](O)[C@H](O)[C@H]2O)cc2c(c1OC)-c1ccc(SC)c(=O)cc1C(NC(C)=O)CC2
b: CC(=O)c1csc(-c2cccc(-c3nc4ccc(Cl)cn4c3NC3CCCCC3)c2)c1.O=C(O)C(F)(F)F
Answer: b. CC(=O)c1csc(-c2cccc(-c3nc4ccc(Cl)cn4c3NC3CCCCC3)c2)c1.O=C(O)C(F)(F)F
