Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.246\% 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: c1ccc(-c2csc(Nc3cccnc3)n2)cc1
b: CCOC(=O)C1=C(C)N=C2SC(C)C(=O)N2C1c1ccc(C(=O)OC)cc1
Answer: b. CCOC(=O)C1=C(C)N=C2SC(C)C(=O)N2C1c1ccc(C(=O)OC)cc1
