Problem statement: Answer the multiple choice question.
Question: Which drug has a 11.928\% 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 other words.
Options:
a O=C(Nc1cccnc1Cl)c1cc([N+](=O)[O-])ccc1Cl
b O=C(/C=C/c1ccccc1)NCCc1c[nH]c2ccccc12
Answer: a. O=C(Nc1cccnc1Cl)c1cc([N+](=O)[O-])ccc1Cl
