Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 32.968% 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: O=C(Nc1ccc(SC(F)F)cc1)c1ccc2nccnc2c1
b: CN1CN(c2cccc([N+](=O)[O-])c2)CN=C1N[N+](=O)[O-]
Answer: b. CN1CN(c2cccc([N+](=O)[O-])c2)CN=C1N[N+](=O)[O-]
