Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 10.608\% 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 additional words.
Options:
(a) CS(=O)(=O)c1ccc(NCCN2CCOCC2)c([N+](=O)[O-])c1
(b) O=C(Nc1ccc2[nH]c(=O)[nH]c2c1)c1ccc([N+](=O)[O-])o1
Answer: b. O=C(Nc1ccc2[nH]c(=O)[nH]c2c1)c1ccc([N+](=O)[O-])o1
