Task: Answer the multiple-choice question.
Query: Which drug exhibits a 17.534\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(C1CCCO1)N1CCN(C(=S)Nc2ccccc2Cl)CC1
b: O=C(Nc1ccc(Br)cc1)c1cccc(NC(=O)C2C3CC4OC(=O)C2C4C3)c1
Answer: b. O=C(Nc1ccc(Br)cc1)c1cccc(NC(=O)C2C3CC4OC(=O)C2C4C3)c1
