Task: Answer the multiple-choice question.
Query: Which drug has a 6.674\% human ether-à-go-go related gene (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] O=C(Nc1ccc(Cl)cc1)c1ccc2ncsc2c1
[b] CCOC(=O)c1c(NC(=O)CN2C(=O)NC3(CCC(C)CC3)C2=O)sc(C)c1CC
Answer: b. CCOC(=O)c1c(NC(=O)CN2C(=O)NC3(CCC(C)CC3)C2=O)sc(C)c1CC
