Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.778\% 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: Cc1cccc2cc(=O)[nH]c(C)c12
b: Cc1cc(C(=O)N/N=C/c2ccc(-c3ccc([N+](=O)[O-])cc3Cl)o2)n[nH]1
Answer: b. Cc1cc(C(=O)N/N=C/c2ccc(-c3ccc([N+](=O)[O-])cc3Cl)o2)n[nH]1
