Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 20.432\% 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. CCc1nn(C)c2c(=O)c(=O)c2n(C)[nH]1
b. O=C1NC(=O)/C(=C/c2ccc(-c3cccc([N+](=O)[O-])c3)o2)S1
Answer: b. O=C1NC(=O)/C(=C/c2ccc(-c3cccc([N+](=O)[O-])c3)o2)S1
