Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.445\% 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(CNC(=O)C2CCC(CNc3c(N4CCOCC4)c(=O)c3=O)CC2)cc1
[b] CC(C)(C)[C@@H]1C=C(C(=O)Nc2ccccc2)O[C@H](OCc2ccc(CO)cc2)C1
Answer: b. CC(C)(C)[C@@H]1C=C(C(=O)Nc2ccccc2)O[C@H](OCc2ccc(CO)cc2)C1
