Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.253\% 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 other words.
Options:
a: Cc1ccc2c(c1)N(C(=O)CCC(=O)NCCCN1CCOCC1)CCO2
b: CCOC(=O)C1C(c2cccc([N+](=O)[O-])c2)C2C(=O)NN=C2CC1(C)O
Answer: b. CCOC(=O)C1C(c2cccc([N+](=O)[O-])c2)C2C(=O)NN=C2CC1(C)O
