Task: Answer the multiple choice question.
Question: Which drug exhibits a 17.558% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCOC(=O)CSc1n[nH]c(NC(=O)c2ccccc2)n1
[b] CCOC(=O)N1CCN(C(=O)COc2ccc3c(c2)C(=O)CC(C)(C)O3)CC1
Answer: b. CCOC(=O)N1CCN(C(=O)COc2ccc3c(c2)C(=O)CC(C)(C)O3)CC1
