Problem statement: Answer the multiple-choice question.
Question: Which drug has a 17.314\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(N/N=C/c1cccc([N+](=O)[O-])c1)c1cccc2cc[nH]c12
b: CCCCC1=C([O-])C2N=CC=CC2=[N+](c2ccccn2)C1=O
Answer: a. O=C(N/N=C/c1cccc([N+](=O)[O-])c1)c1cccc2cc[nH]c12
